You're talking a lot of cameras and a lot of real estate. I don't think that is logistically possible given the random nature of the shootings.
You Bet. Well, anything is better than nothing. Maybe by chance the Killer goes down a road that does have cameras. BTW, I recognize the privacy issue here but as long as our government sees fit to let ANYONE and EVERYONE in this country we better be thinking better surveillance in our cities and towns.
Even if this particular Killer does not turn out to be a ME Terrorist, I am sure AQ and others are watching this with interest.
If the shooter(s) really do have the cops totally confounded there's one approach that might bear fruit. If they have reason to believe that he/they are using the main highways to either enter or egress from the target areas they could install traffic cams at the on/off ramps of the exits. I'm pretty sure there are some wireless solutions out there so running cable (time consuming and expensive) could be avoided. The cameras connect to an always monitored central facility. Tape record all camera activity and archive. If a shooting takes place review all camera feeds for suspect vehicles. You may not get success the first time but eventually unless the perp(s) are switching vehicles all the time you're going to see the same one or two vehicles consistantly either entering or leaving the area via the freeway exits in close relation to the time of the attacks. Proceed to apprehend as possible. Might seem like grabbing at straws but unless they have more to go on than they're telling us (and I suspect they do) this could yield benefits. Pick some key traffic flow points and hope for the best.
Only problem with using cameras is they don't currently exist in this area if I'm interpreting people's posts correctly. That means they have to be installed. Hard to do with no one noticing, plus the cameras may be visible after installation. In this case the perp simply changes their pattern or moves outside of the coverage area.
I wish I had a viable answer to this problem. I suspect we all do.
