David Milliband's lack of perspective

Yesterday Labour leader candidate David Milliband showed a shocking lack of perspective in his below twitter post.

Clegg says govt "acted wrongly" in 1972 in not investigating Father Chesney case. So why no investigation into Coulson?

So David a few questions for you.

1. How many Labour MP's where killed by Andy Coulson?
2. Considering that no final decision has been taken as to whether there will be an investigation why do you feel it is appropriate to claim that there will be no investigation of Andy Coulson.?
3. Why do you think it is apropriate to compare murder with an invasion of privacy?

I have e-mailed these questions to David milliband and will wait to see if he replies.
