If he did it in the lords he is immune from prosecution and the police are taking the piss - as usual - if they try to intervene there.
Interesting to see if they really go after him or just try and bluff it. Bluffing wont work so i guess it will either come to nothing, they make a public fuss about it StreisandEffect.lol
or they try to get him on something else? If they arrest him on kiddie porn in a few months well know why. . .
