I would support such police action.
I also think it would be very appropriate to post how long a rider has been riding, or how long they've owned that bike, who is involved in any accident. Especially those who fail to negotiate the road properly or lose control on the road. Sometimes the news reports here mention that... or used to... and it is very enlightening how many novice riders think they are invincible and end up in accidents alone or with others. But I guess those who scream about privacy don't want anyone to know that proper training was not received or followed.
