Why is the birth date of the Danforth shooter too personal to make public?

I don’t pretend that this is the only thing about Faisal Hussain that Toronto police and Ontario deputy Crown attorney John Scutt want to keep secret — his birth date, for God’s sakes — but it is the most telling.

All bureaucracies tend to secrecy over time, the police are no different but this smells of PC censorship and implies there is something to hide.
