SEC. 3600. FINDINGS. (a) Persons under the influence of an alcoholic beverage or drug frequently lack the normal restraint and judgment that would ordinarily prevent them from initiating or escalating criminal or domestic violence. (b) Carrying or possession of firearms by persons under the influence of an alcoholic beverage or drug exacerbates the problems associated with the irresponsible or unlawful use of such weapons. (c) It has been determined that in order to promote and to protect the health and safety and welfare of the public, it is necessary to regulate the carrying or possession of firearms by persons under the influence of an alcoholic beverage or drug.

(a) Upon the trial of any criminal action, or preliminary proceeding in a criminal action, pursuant to Section 3602, the amount of alcohol in a person's blood at the time of the test as shown by chemical analysis of that person's blood, breath or urine shall give rise to the following presumptions affecting the burden of proof: (1) If there was at that time less than 0.05 percent by weight of alcohol in the person's blood, it shall be presumed that the person was not under the influence of an alcoholic beverage at the time of the alleged offense. (2) If there was at that time 0.05 percent or more but less than 0.10 percent by weight of alcohol in the person's blood, such fact shall not give rise to any presumption that the person was or was not under the influence of an alcoholic beverage, but such fact may be considered with other competent evidence in determining whether the person was under the influence of an alcoholic beverage at the time of the alleged offense. (b) Percent by weight of alcohol in the blood shall be based upon grams of alcohol per 100 milliliters of blood.
(c) This Section shall not be construed as limiting the introduction of any other competent evidence bearing upon the question whether the person ingested any alcoholic beverage or was under the influence of an alcoholic beverage at the time of the alleged offense.

The test shall be incidental to a lawful arrest and administered at the direction of a peace officer having reasonable cause to believe the person had upon his or her person a firearm in violation of Section 3602. The person shall be told that his or her failure to submit to, or the noncompletion of, a chemical test will result in the confiscation of the person's firearm for a period of six months. (2) The person arrested shall have the choice of whether the test shall be of his or her blood, breath, or urine, and the person shall be advised by the officer that he or she has such a choice. If the person arrested either is incapable, or states that he or she is incapable, of completing any chosen test, the person shall then have the choice of submitting to and completing any of the remaining tests or test, and the person shall be advised by the officer that the person has that choice. (3) If the person is lawfully arrested for having upon his or her person a firearm while under the influence of an alcoholic beverage or under the combined influence of an alcoholic beverage and any drug, and, because of the need for medical treatment, the person is first transported to a medical facility where it is not feasible to administer a particular test of, or to obtain a particular sample of, the person's blood, breath, or urine, the person shall have the choice of those tests which are available at the facility to which that person has been transported. In such an event, the officer shall advise the person of those tests which are available at the medical facility and that the person's choice is limited to those tests which are available. (4) The person shall also be advised by the officer that he or she does not have the right to have an attorney present before stating whether he or she will submit to a test, before deciding which test to take, or during administration of the test chosen, and shall also be advised by the officer that, in the event of refusal to submit to a test, the refusal may be used against him or her in a court of law. (5) Any person who is unconscious or otherwise in a condition rendering him or her incapable of refusal shall be deemed not to have withdrawn his or her consent and such a test may be administered whether or not the person is told that his or her failure to submit to, or the noncompletion of, the test will result in the confiscation of his or her firearm. Any person who is dead shall be deemed not to have withdrawn his or her consent and such a test may be administered at the direction of a peace officer. (b) If any person refuses the officer's request to submit to, or fails to complete, a chemical test, the officer shall confiscate the person's firearm for a period of six months.

For the purposes of this Section, the scope of the hearing shall cover the issues of whether the peace officer had reasonable cause to believe the person had upon his or her person a firearm in violation of Section 3602, whether the person was placed under arrest, whether the person refused to submit to, or did not complete, the test after being requested by a peace officer, and whether, except for the persons described in Subdivision (a) who are incapable of refusing, the person had been told that his or her firearm would be confiscated if he or she refused to submit to, or did not complete, the test. (d) Any person who is afflicted with hemophilia shall be exempt from the blood test required by this Section. (e) Any person who is afflicted with a heart condition and is using an anticoagulant under the direction of a licensed physician and surgeon shall be exempt from the blood test required by this Section. (f) A person lawfully arrested for any offense allegedly committed while the person had upon his or her person a firearm in violation of Section 3602 may request the arresting officer to have a chemical testmade of the arrested person's blood, breath, or urine for the purpose of determining the alcoholic content of that person's blood, and, if so requested, the arresting officer shall have the test performed. (Added by Ord. 399-82, App. 8/12/82) SEC. 3606. ADMINISTRATION OF TESTS. (a) Only a physician, registered nurse, licensed vocational clinical laboratory technologist or clinical laboratory bioanalyst, or certified paramedic acting at the request of a peace officer may withdraw blood for the purpose of determining the alcoholic content therein.

The failure or inability to obtain an additional test by a person shall not preclude the admissibility in evidence of the test taken at the direction of a peace officer. (c) Upon the request of the person tested, full information concerning the test taken at the direction of the peace officer shall be made available to the person or the person's attorney. (d) No physician, registered nurse, licensed vocational nurse, duly licensed clinical laboratory technologist or clinical laboratory bioanalyst, or certified paramedic, or hospital, laboratory, or clinic employing or utilizing the services of the physician, registered nurse, licensed vocational nurse, duly licensed laboratory technologist or clinical laboratory bioanalyst, or certified paramedic, owning or leasing the premises on which such tests are performed, shall incur any civil or criminal liability as a result of the proper administering of a blood test when requested in writing by a peace officer to administer such a test.

The fact that any person charged with carrying upon his or her person a firearm while under the influence of any drug or the combined influence of alcoholic beverages and any drug in violation of Section 3602 is or has been entitled to use the drug under the laws of this state shall not constitute a defense against any violation of the section.
