Eh, I was more along the lines of, "it might look suspicious because most IDs have the picture printed in them instead of taped on, so having something taped on might just be weird to see period." Depends on how you design the ID though.
Yeah, I think once you develop your main character, you'll find it easier to write with him, too. It's a lot harder to write someone in someone's perspective when you have no idea what their personality is like.
I'm not sure where you live and how your legal system works, so we might differ. Generally, though, some crimes are rated "low," like petty theft, simple assault, trespassing, and drug possession. Punishments are usually monetary fines, probation, community service, or short jail time. Sometimes there's a longer prison sentence, but I think those are "higher ranked" misdemeanors. Age plays a role, yes, along with his prior record. If it's his first crime, I think they generally go easier on you. Burglary and robbery are kind up ... well, I think you might get jailed for that, but I'm not sure on that myself. =P It depends on the degree. I think "petty theft" is on the lower end of the spectrum while robbery is on the higher end.
Erika sounds like the right person to do that sort of thing, sympathize and try to understand a person.
Also, thanks for the review (and a biggun too). =) I'll respond to it soon, lol.
