Would you have a similar view if police were pointing out the risk of bike theft and handing out vouchers for locks?
Yes, I think I would. We seem to be moving towards a culture of blaming the innocent.
Had your bike stolen? - that's your fault for not locking it up.
Had your car window smashed? - that's your fault for leaving your ipod on your car seat.
Been assaulted? - that's your fault for going into town on a Friday night.
Been mugged? - that's your fault for walking home alone at 3am.
I'm pragmatic enough to realise that it makes sense for me to lock my bike up, not leave my ipod on my car seat etc etc and I nearly always wear hi-viz when riding (my decision, for whatever reason). These things are all my personal choice, but if I choose not to do them I object strongly to being made to feel guilty if someone else steals my bike, smashes my window or knocks me off my bike.
The bottom line, IMHO, is that too much efort is put into coercing the innocent and not enough effort put into catching the guilty.
In the case of the OP there will be a number of police officers handing out the hi-viz gear. What I'd like these police officers to do instead would be to accompany a commuting cyclist, note the inevitable left-hooks, SMIDSYs, close passes etc then 'have a word' with the offending drivers. I think this would be more effective and importantly it would target the guilty, not the innocent.
