Collective punishment for thee, understandable anger for me

'Human-rights groups such as the Israeli group B'tselem have described the demolition of houses as "a clear case of collective punishment which violates the principle that a person is not to be punished for the acts of another".'

Whereas murdering innocent motorists and bus passengers is apparently not collective punishment... 'Last July, Dwayat used a bulldozer to smash into cars and a bus in central Jerusalem, killing three and injuring more than 40.'

Do these people have any sense of irony?
