To some extend, a criminal with nothing to lose don't necessarily stop just because they get caught.

And for most of us, any risk to health or wellbeing isn't worth taking. You have something to lose the desperate criminal drug addict might not.

Granted, hardening your property against burglary is pretty low risk. There is no reason not to have 3 point doors and windows.

Just don't harden it so much that a determined firefighter can't get in :)
