It's almost at the point where if you rapping and got money like that, if you ain't with security you might as well have that hoe stuck in yo hand just to try to deter a thief from making a move. Legality varies state to state but i feel like there should be a "free handling" license for people with proof of how much they have to protect.
They weren't with security, had a gun (illegally), and it didn't matter. Being armed isn't going to save you if someone gets the drop on you and starts shooting.
Either have security at all times, bulletproof your vehicle, or better yet stop instigating beef. If this is related to his issues with HBTL Tjay was the one pushing for those problems.
