We could be using trained dogs, but aren’t because Muslims don’t like dogs sniffing around them....not making this up. Boo Hoo - sorry to offend you.
The bonus, once some photos of porkers snuffling around the tender bits under a few burqas and dishdashas make the internet, would be a muslim free airspace practically overnight. Only exceptions: All passengers boarding El Al flights (they have perfected the art of profiling and don't need our help) and however many kosher charters our Orthodox Jewish friends might like to organize.
