yea you cant hide anything like that in a suitcase, the second it went into the x ray machine you would be hauled away, your bag blown up in a controlled explosion and bam! you're in guantanamo bay!
Yeah, I went to the US with a bunch of handheld RF devices and barcode scanners in my bag (my company installed them) in 2000 and I guess in the x-ray looked suspicious. The security officer asked what was in the bag and I told him while I brought one out to show him. He freaked out and thought I was going to detonate or something then told me never to open a bag - "WE open the bags". I wonder what would have happened to me if this was AFTER 2001?
