One trueism is that IF an apartment complex realizes they have enough of a problem to need security gaurds, the problems are really so bad, they need off duty local LE .
I talked to a supervisor for the company that does security for the apartments I live in once. I asked what their armed pay was, she wanted to know why I asked and I told her our armed guys made 15.00 and I wanted to see if I could do better with them.
She looked at me like a starving dog at meat and told me I wasn't gonna get 15.00 bucks from her employer.
The guys that check our apartments are all unarmed and make about 10.50$ to work in a neighborhood where I won't walk out the door unarmed
