The problem is being addressed, who knows how long it will take and if the problem can be solved at all.
One problem it doesn't solve is the same thing I have brought up over and over again, but let's sing the refrain again for your benefit:
Scanners and Body Searches Don't Detect Bombs.
How do you address this very significant problem? And how to your rectify the fact that trained bomb sniffing dogs do detect bombs, and do so without bringing the 4th Amendment into question, as they are a passive system that is already used by police, border patrol and customs agents.
body scanners and frisking can find bombs attached to the outside of the body, but a very thin argument used earlier in the thread was that the scanners can't find bombs implanted within someone, medically or otherwise. Is there anything to suggest that sniffer dogs would be able to smell these implanted devices?
Another thing sniffer dogs rely on is the knowledge of what explosive compounds a terrorist would use, if a terrorist was to use a compound unfamiliar to the dogs then they wouldn't be able to pick it up either, rendering them just as moot as the scanners in that regard.
there is no silver bullet to this issue.
