Gun Sniffing Dogs???

Bearing Arms - Gun-Sniffing K9's: The Future of Gun Violence Prevention...

I dunno... I get how/why the article says they want to use the dogs to search for guns, but I'm concerned with potential for abuses. Specifically, will these dogs be used to discourage law abiding citizens from carrying concealed, especially where they are licensed to do so? Will they have a bunch of these dogs in crowds just searching for people who are carrying concealed, in an effort to harass them (i.e., stop, detain and interrogate anyone carrying concealed, demand their CWFL, etc.)?

I think Amtrak uses dogs like this already.
