First of all, if it isn't paranoia, then it seems like these guys would've done something by now. How long have they been posting up outside of your house? Few weeks? "Gang banger" thugs don't have enough guile to properly case a place out. They'd give it a few days (maybe a week) to see if they can identify how many people are coming and going (to try and see how many peeps deep you be rolling wit'), unless they knew you/knew someone who knew you, in which case they wouldn't case the place they would just try and get that information somehow else.
But chances are (if they actually are casing you) that they are a bunch pf dumb-fuck low life's, and they would've already made the hit.
There is a such a thing as a HEALTHY paranoia. It can save your life. But don't let paranoia keep you from using a logical thought process to figure out what's going on. Take it from me, I've openedy door to a smack in the face from a wooden baseball bat, followed by me fighting off 5 dudes-- 2 of them had bats, 1 of them had a tire iron. I posted pictures before on another thread when I first started out.
Now, luckily for me I'm somewhat of a miracle man and I managed to keep them from getting a RED HEADED FUCKING CENT from me, and after they stopped attacking I chased them a half a mile down the road and ID'd the getaway car.
Right now 4 of the five are still in prison, and when they get out they owe me 13,000 I'm restitution money. It caused a lot of bullsgit for me; everyone in the community labeled me a "drug dealer" BC I was broken into and attacked by 5 black guys.
Even to this day, I'd rather have junkies scoping my place than cops. Like someone else said, worse case scenario they take your shit. You don't have to fight them, if you aren't willing to take an ass whooping then just scream "take it all just take it, I'm an actor don't mess up my face". Me personally, I'm from the south and if someone's gonna bust in my house to take something, the first fucking thing they're gonna have to take is my fucking life. Most of the time they aren't willing to do it, and sometimes honestly it can help a man out to take the occasional ass whooping. Helps him keep perspective.
At least thugs won't lock you up in a concrete box like a dog for a chunk of your lifetime.
