Stand still - and accept it ! If they have grounds to carry out the search - and you try to stop them - you can be charged with obstruction !
Yes, you can be.
With probable cause, yes he can.
Only if they don't have probable cause.
yes, but only after they arrest you
No, loud music does not establish probable cause to search your car. Unless the cop has a warrant or your permission to look through the car, the search is illegal. Always remember, if a cop says, "Do you mind if I take a look through the car?" or something like that, it means he doesn't have the right to search your car without your permission, so you should always say, "no." Saying "no" doesn't give him the right to search the car. It means he can't.
yes and no
First he will have to show his I.D card, second he must have a proper warrant to search your house, if all this is not there he can stay out.
The question does not contain enough information to allow a reliable answer to be made.
yes, because it is still a cop's car... he/she just isn't in it at the precise moment.... my car is still my car even if I'm not in it
That seems to be probable cause to search, so I'd say yes. Although it depends on your state laws.
Totally! He is a cop =D
not if you let him search it
