Bikejacking on Kingsland Road

Given the inevitable knee-jerk D-lock response that these threads prompt, have any proponents of this form of justice actually D-locked anyone? If not, is that a) lack of opportunity, b) fear of legal consequences, c) don't mean it really, d) you're just a hero behind your PC?

Just asking.....

Surely this is not really justice, you are attacked and you have a right to reasonable self defence - anyway, d-locking is a bit cumbersome
