It is an increasing problem. I've been 'hit' three times in the last year, and once was on a really nasty approach with other s**t going on and could have been very unpleasant indeed. One has to question why these things are so readily available, whereas other potentially lethal weapons are not.
IMHO it is only a matter of time before the inevitable happens. Pray God it doesn't, but seriously something needs to be done. Six months is a joke frankly. It is a wilful act that amounts to intent to murder a substantial number of people.
