I have heard that a aluminum case went through a metal detector at a airport and the smuggled in 20 pistols with that aluminum case because the aluminum reflected it or something idk please help soon! :D
Well, lets brain this out together. We know that aluminum is metal, so it will set off a metal detector. Now, if a guard at that metal detector gets lazy and fails to open the case, well then yes the guns go undetected. But if the guard is doing his job, then he opens the case and the bad guys go to jail. Now lets pretend that it went through an X-Ray machine. The X-rays go right through aluminum and the guard would see the contents of the case. Only lead can stop X-Rays, and if that aluminum case had a lead lining the guard would again demand that the case be opened. Honestly, brain work and common sense are on the decline.
