This doesn't always happen but damn every other package I get looks like someone played football with it. I even got a package once that the entire side was ripped off. All they did was put a sorry note with it and taped it back up. I don't know if that should make me worried or they're just jackasses. I know that the postal place (whatever it's called) that my stuff goes to before it goes to the destination is notoriously bad but damn I'm worried to order anything fragile cause they'll just break it. I've tried calling them before too and I was on hold for a fucking hour and all I got was a "you will have a returned call in the next 48 hours" which I never got.
EDIT: I should also add it really doesn't look like someone is trying to look inside although maybe a tiny corner of the package you can see through a little bit. It literally just looks like someone had beef with my package and beat the shit out of it.
I've had some mail come beat up as fuck, and other mail come looking pristine.
One time I received a package that I ordered off of Agora (can't remember what it was though) and the bubble mailer literally had a big black shoeprint from some sort of boot on it, right on top of the shipping label.
Your mail isn't being looked through if it comes to you looking beat up, LE doesn't want people that they put under surveillance to know they're being watched. If they're watching someone, they want them to fuck up in front of them and catch them in the act. If they made it obvious that they were watching someone, don't you think that would go against their agenda?
