Here, we consider the entire state to be a prison.Guido's gonna be spending a spell in (what's a famous prison in Jersey?).
If they haven't released his name yet, there is an ongoing investigation. They are checking his phone and laptop for accomplices and associates, on both ends of his trip. There could be a language barrier, or they are waiting on a warrant to search his house.
Finding an assembled AR with an X-ray should be routine. I'm sure they see several every day. I'll give them credit for noticing that is wasn't packed properly and declared.
Once, in London, I got pulled off the Concorde (yea, I'm old). The screeners had noticed that I had several small 2-way radios in my checked luggage. I had to open my suitcase right there on the tarmac. I always zero out the radios for safety when on an aircraft (Army habit), so everything was fine. I give the screeners credit for that one. Good catch.
Twice, as I recall. If you needed to cross the puddle on short notice, you could always get a seat on the Concorde. Each flight was only half full. You had to sit in certain seats for takeoff, so you didn't cause any trim issues.Cool that you got on the Concorde. That’s a wish I always wanted to do.
