I never ceased to be amazed by the casual dismissal of a death because the person who has died is a criminal.
That is not to excuse criminal behaviour, but the standard 'one less/ got what was coming to him/ shan't lose sleep over it ... ' responses that always crop up when this type of incident occurs, truly say more about the poster than the deceased.
I could never be so cavalier about the death of anyone, no matter what they had done, and to pre-empt the inevitable - it has been my house on two occasions in separate homes that have been defiled by intruders, but that does not and cannot mean that I would casually dismiss the death of another human being like this.
To do so diminishes me as a person, so I simply don't think that way.
