It's a choice if you can handle yourself and fancy yourself as sharper than the average Joe. Quick route to money, a few cars and birds who like beak. The flip side is you're waiting for your door to get kicked in (and you better hope it's plod) and eventually you'll end up inside with harder people who will eat you alive. If you manage to overcome those hurdles you spend your days watched and even worse, watching. No trust in anyone, justifying it to yourself until eventually you're either back inside or badly done in.
Mugs game. These little dweebs in balaclavas bouncing round town, flipping scramblers through the street etc.... if only they knew how pathetic they are.
