We have reasonable force over here too. But a lot of people think it is perfectly acceptable to kill burglars. Yet unless it was a genuine case of self defence they would not because they would have too much to lose. As it is a bit difficult to see your children when you are doing life for murder although for obvious reasons juries are generally sympathetic. But from time to time they return a guilty verdict. Most intruders - if the intention is to steal - do not actually want confrontation as that will slow them down. All they want is a quick entry taking what ever is available and an equally quick exit. Grappling with the owner is not part of the plan
