Sorry about the thread drift, but if you could indulge me a bit further...
It's not that the techs would be deliberately shot at but that the equipment would be shot at from some distance while the techs were attending.
It's a large target so pot shots could easily be taken from 1000m away. Would you like to be inside a thin skinned building where there's a known history of people taking pot shots?
What I'm trying to get my head around is that the response was an OH&S issue instead of a police issue.
I'm really struggling with the concept that if you'd gone to VICPOL and explained the issue as you've explained here that their response would have been nothing?
DIVOSH!
