when cops do a real bust, they take a lot of pictures of the 'crime scene', there's sometimes a cop recording the whole thing....
they also call the news. be it a small local newspaper reporter, or a full-on Live broadcast.
if you didn't see anybody taking pictures, numerous people recording the crime scene meticulously, then it wasn't a real bust, and probably somebody on that side was doing something illegal, and you're screwed......
in terms of your landlord being able to enter your property, if he gives somebody a key, they can go into your apartment. you can try and argue technicalities but you are better off saving the time and money.
the landlord has to give you notice to kick you out...
on your next lease you may want to negotiate you getting 2 week notice to vacate, or 30-60 days notice...
