There is nothing “technically” about your theft being illegal and nothing about the “transaction” is even remotely “legitimate,” regardless of what paperwork you fabricated. You are a common thief – and, apparently, an unremorseful and unrepentant one at that. Luckily for your victims, you don’t seem to be very good at it, or even very bright. So, your criminal career is not likely to be very long or successful.
That being said, Ron’s advice above is sound. Jail is a very real possibility (along with other life-long consequences). You are just going to have to wait and see how long it takes to be caught for your crimes and, when it happens, don’t talk to anyone but your attorney.
Behind the badge is a person. Behind the person is an ego. This is as it should be, person at the center and ego to the back.
