Even with regular zip ties #2 looks more likely to hurt you than get you free. Even crappy zip ties are tough, and he's just banging the things against his belly. Plus, is it typical for your arms to be tied together in front of you? This technique won't work at all if they're behind you.
The #1 option would only seem to work against someone who does a bad job of putting them on in the first place, so you're left with #3. I imagine proper LEO ties have extra bits that make that method less reliable.
A better option might be a small concealed blade somewhere on you, preferably somewhere reachable with your arms locked together, and try not to slice your wrists open by accident.
