Yeah - lots. You can’t help but watch your back every minute that you are on the job. There just may be someone waiting for you around the corner. And what if you really offended this gang or that gang’s top drug dealer? (They’re a pretty sensitive bunch, so it isn’t outside the realm of possibility.) It’s likely his brother, who is now out of prison, knows your name, your address, and where your kids go to school. And chances are he is not just going to use this information to buy them textbooks.
