An Anti-Sniper system similar to this SENTRI surveillance system was discussed a few years ago during the Bosnia conflict. It seems sniping was a national pastime and no one, and I mean no one was safe. The version I read about though did more than take a photograph, it fired .50 cal rounds at the sniper making this easy game a bit more dangerous. How that more challenging version was received I don’t know.
Now it appears it is being rolled out in the big cities in America. Sadly, without the .50 cal. I wonder why? Like the UK, I though these places had gun control programmes. Funny how they don’t seem to work wherever they are implemented.
Looking at all this security stuff makes it look like the place to be in. The money for terrorists, bad guys and just plain security seems to be growing every year. I think I need to reconsider my plans.

The point five-oh would be sufficient for the job. Why the round is not used in the package is because haf of Washington might go down in a hail of fire.
and the downside is?
