Listen, I’m not going to go off half-cocked on this. If law enforcement knocks on my door asking me to give up any weapons, I’ll tell them to come back with a warrant.
If they come back with a warrant, come on in. If they come back with a SWAT team at 3 AM because I told them to come back with a warrant, and they don’t announce themselves when I come to the door, then I’ll assume some reprobate is on the other side of my door at 3 AM.
You don’t break down peaceful citizens’ doors in the early morning hours and expect to not get shot at in my neck of the woods.
*shrug* There have been multiple occasions that the San Jose PD has been here. I've been awakened by them at my bedroom door at 2:30 AM, I've had them knocking on my front door on a couple occasions very late at night, sometimes armed for bear. I've allowed a warrantless search for drug manufacturing paraphernalia, they've done a warrantless search of one of my roommates bedroom. (They apparently don't need a warrant to search you if you are on parole).
Fully half the fix-it tickets and moving violations I've gotten in my life (one of each) were issued by the SJPD.
That being said, I like the SJPD, they have invariably been at the highest standards of professionalism, courtesy and respectful treatment of all.
LAPD? Arrogant scum on nearly every single occasion I've had the displeasure of being in close contact with them.
