1. How is that punk going to know you have a bitcoin account?
2. Why would he risk prison time for what might be 5 0.05 bitcoins?
3. How long will he stand in the street and threaten me, waiting for the password? Remember, if i get a concussion, i might forget the password.
4. Android app can have a feature that gives the thief access, but to a secondary (honeypot account) with only a small amount of BTC. If the thief wants to beat you to a pulp in broad daylight because he thinks you gave him a honeypot account, more power to him.
