I guess as you are the man on the scene, it's down to you to decide just how negative you can make what I said sound. I'd tell them that just because they haven't heard anything it doesn't mean that nothing is being done. My experience is that people get on with the job in hand and don't go in for tea and biscuits calls. Maybe I don't know what I'm talking about, maybe a free excursion with every attempted sexual assault is the way to go.
I don't apologise for anything I have said here, people called for police reaction and action, and now they have it, it isn't how they'd like it. Give them a break and let them get on with finding this filth.
