Don’t be SILLY, of course you can! BUT you can be charged with drunk in public...., drunk and disorderly and i am sure other laws, depending on the town/state. Welcome to the Litigious US of A
Chances are they won't give you a hard time depending on your attitude; however, if they feel you are intoxicated to a point where you present a danger to yourself or others then yes, chances are your going for a ride to the "drunk tank" to sober up and get a $50 D & D (CPC 647 f “Every person who commits any of the following acts is guilty of disorderly conduct, a misdemeanor…Who is found in any public place under the influence of intoxicating liquor, any drug, controlled substance, toluene, or any combination of any intoxicating liquor, drug, controlled substance, or toluene, in a condition that he or she is unable to exercise care for his or her own safety or the safety of others, or by reason of his or her being under the influence of intoxicating liquor, any drug, controlled substance, toluene, or any combination of any intoxicating liquor, drug, or toluene, interferes with or obstructs or prevents the free use of any street, sidewalk, or other public way.”
There use to be a time they would just give you a ride home, but with all the law suits etc... many police department just follow the procedure to cover their own butts.
