Police spotting (junction watch)

I had two seperate instances of police enforcing the cyclist box at junctions this morning: Quoth one at Stockwell speaking to a motor cyclist "you must be a right idiot pulling in here right in front of me" he the proceeded to make him wheel it back out of the box.

Now a good start would be similar enforcement efforts every day for the foreseeable future

Unfortunately I cant see old bill standing on the streets en-force reprimanding every motorist that brazenly pulls into that box every day. Its also "illegal" for cyclist to enter this box not through the broken line on the inside (promoting dangerous undertaking). Cameras to catch number plates and consistent fining however... I read an article a while back that TFL were going trying to take over the duty of carrying out these fines (as they did with the yellow box junctions and bus lanes, do you see anyone in these?). Anyone know anything about this?
