This isn't the west where you worry about a small percentage of semi-professional burglars. This was a pretty massive number of fairly amateur burglars who did it simply because it was easy. If you did nothing then you'll get robbed by them due to sheer numbers. Guaranteed. If you do something then you'll face the much smaller percentage of more professional burglars. Then you're only somewhat likely to get robbed.
