Here's a couple of ideas to kick around, apply in another way.
Maybe it's only bigger cities, but do most of you guys see these police watchtowers around your town?
To tell the truth, I have never seen ANY sign that ANY was manned,
or that the parking lot is being watched by someone in person,
but I also heard of volunteer watchers. With remote cameras now days
maybe they don't need to be manned. Point is the police move them around,
I'm sure if they own 50 of them none are ever stored away, all 50 are sitting
on station somewhere looking ominous to the gremlin, who never knows if someone is watching.
In this day and age, I wouldn't be too opposed to a remote countermeasure or weapon system,
if not a real remote control gun, although I think that is probably very doable,
at least sirens, cameras, speakers, spotlights and maybe lasers for distracting or blinding an assailant,
maybe an industrial-strength paint-ball gun for marking an assailant
or direct impact teargas pellets similar to a paintball gun, etc.
In the same vein of thought, these units here could be deployed in schools malls
sporting events churches and other soft targets. It goes hand in hand with
anti-terrorism efforts. There public would know that in every place where this monitor is seen,
there is a control room onsite to accomodate an armed guard ready to respond.
There again, remote monitoring could be rotated with a live watcher, so there was
a deterrence effect greater than the real manpower needed.
