Yes but for a shirt? Capturing a shirt shoplifter is worth the same effort and potential damage to innocents as a murderer? Or a bank robber? Or an organized group hitting electronics retailers? If someone refuses to pay a parking ticket, how much collateral damage is worth getting them to pay their ticket?

Also I feel your comment may be implying that this sort of hyper aggressive enforcement is the only thing keeping crime down - I would suspect that crime at the level of shoplifting a shirt is more often due to need and desperation than to purely malicious intent, and while hyper aggressive enforcement may have some deterrent effect those crimes would probably be better resolved by trying to eliminate the core issues driving them in the first place.
