This illustrates the problem of people taking the law into their own hands.
So many times we heard people claiming the right to do so. Like those who say it's OK to pursue burglars who break into their homes, rapists, child molesters etc.
It is only when an instance like this is high-lighted that we can see clearly that there is almost always a problem with identifying the perpetrators. It is all too easy for innocent people to be targeted.
If we are dissatisfied with the way convicted criminals are dealt with under the law we need to lobby our (your) MP and get the law changed, so that it reflects the wishes of the electorate. But don't hold your breath, I know hardly anyone has, or will, go down that road. Most prefer to just complain the the converted.
There are exceptions to this generalisation, that's why they get the laws changed, often by the vociferous minority against the wishes of the silent majority.
