What do you really want them to do? If it is their vehicle and they live there as long as when the officers show up there is not drugs in plain sight or the open containers or keys in the ignition if they are drunk, then there is not alot to do except ID the person and tell them to go inside and dont cause trouble.
I am not trying to argue with you at all I understand living in a crappy area and having troubles but there are rights even for scum bags the 4th amendment does not allow for searches whenever police want.
Sucks man....trust me I know
