The tabloid press and social media are doing their best to convince themselves he'll be locked up for 25 years, key thrown way, etc, etc, while the burglar's mate get's a free pass to the local brothel or something.
In reality, it's standard procedure, just in case all is not as it seems.
As you say, even in America, "there will be some investigating to make sure it's not a wife's former boyfriend and you decoyed him into the house to shoot him, "
That's what's happening here, but people just love to find something to be outraged about.
I have to read all the post on here, and sometimes I find it very depressing....
