What planet are you on? Can I come live there?
In Britain this situation happens all the time.

"What percent of burglars are 1) armed 2) looking to fight not run and 3) doing b and e at 3 AM when you can be sure there is no one home by knocking at 10 AM?"

1) Armed with a tool of some kind that can do damage to your person? About 100%, give or take.

2) I'd say it's about half and half. Personally, I don't like those odds.

3) All burglaries happen at 10am? That's handy. Do the police know about this? I must say, it's jolly nice of Mr Burglar to be so methodical.
