They have satellites and drones that can map everything relatively quickly, recon isn't the hard part. Topographical data doesn't win hearts and minds.
Like I said, I'm not against gun control though. I just feel like blanket "no guns!" statements aren't really productive to the conversation. It'd be like trying to discuss abortion with a Christian and demanding "abortions on demand up to 10 months no questions asked!"
It's just such a dismissive, "my way or the highway" take that it makes reasonable discussion impossible and guarantees gridlock.
