Nobel Terrorist Cell?

My husband was nearly arrested at Arlanda

International airport due to a laser pointer I bought him. He had travelled to Sweden, going through security at Logan and at Heathrow, no problem. Trying to get home was another matter, The pen shaped device with batteries in it caught the attention of the sharp security agents at Arlanda. (Nothing gets past a Swede!) Ah ha! A LASER POINTER! Great scott! He must be planning to give a power point on the plane! That was it. Passport confiscated, police by his side; it looked bad for a return trip and more like a trip to jail with a call to the embassy. A colleague travelling with him suggested Jack "play the Nobel card." Instead, he showed why he got the Nobel, i.e., he's kind of smart and he believes in doing the experiment. He suggested the security personnel point the laser at the floor to test its strength. They did, gave it back to him and he got on the plane. Good thing they didn't know blue violet light is highly scattered and so in a bright place it will appear dimmer (less powerful.)

I do wonder, what is the fear, that he will conduct surgery on the plane? He was 30 to 100 watts shy of the power to do that. Perhaps the blue beam made them fear it was actually a sonic screwdriver? That seems more likely to happen at Heathrow, somehow. If anyone does know the reason for this embargo, please share.

addendum: A friend asked me if it would have worked, Jack saying he was a Nobel Laureate. My initial response was that it probably would have ticked them off. But then I realized, this was Sweden, land of the Nobel. I'm not sure it would have gone much differently, but on the off chance they weren't willing to test the laser, trotting out that particular credential may have moved them. Anyway, they were more sensible than I can imagine TSA agents being. Discretion has become a dirty word in this country.
