Er yes......Was caught smuggling explosives into the UK (Wait, wait.......please read on.....honestly not as bad as it seems).
I was 14 and was lucky enough to go on a school trip to Switzerland. Our school went with about 4 or 5 other schools all of who were older than us. In any event in Switzerland my friends (but no me!) bought thousands of these small fireworks, small enough to light and hold in your hands. In any event on the return journey we came back though France over a channel crossing and into Victoria Station in London. Our luggage was somehow delayed and was coming into Victoria on a following train. The teachers with our party said they were going to see some sights in London (I suspect that they went for a beer). This left 10 or so of us on Victoria station for an hour or so and some bright spark (

) thought it would be extremely funny to let some of the fireworks off. I had a walking stick (a souvenir) with a hole in the end - a perfect size to put a firework in and ignite. After about half an hour or so of this "fun" our small group was surrounded by what I recall as 20 or 30 (it was probably 2) special branch officers (I suspect they were British Transport police, but to me they were Special Branch). I was identified as the "ring leader" and marched into an interrogation cell (well an office in any case) where I was questioned by an officer with epaulettes on his shoulder (at 14 with no "previous" I assumed that he was probably a Commander (at a minimum)).
Special Branch Commander: So how many of these fireworks do you have?
Me: None
Commander: So where did you get them?
Me: I can't remember (I was not going to be a rat and in any case if i had I would have been beaten to a pulp)
Commander: I have broken harder men than you (said as he slapped his cane in his leather gloves)
Me: Whimper (I had tears in my eyes)
Commander: I hope that you know that bringing explosives into the country is a very serious offence. ( I am sure now that he must have been laughing with his other colleagues but I did not see this)
Me: Louder whimpers (and thoughts of doing a long stretch)
He then said that he would search my hand luggage where I had 2 ash-trays "borrowed" from the Hotel Lucerne of wherever we were staying. Now I knew it ... it would be a very very long "stretch". The Commander then said that he would be searching all the luggage (from all of the schools) when it did arrive. Now it was getting serious. The other school kids were all older and from (what I assumed) were some of the hardest schools in London. I knew, as they had been boasting about it, that they were smuggling in large quantities of cigarettes and alcohol. As they came back they found out what had happened and they were none to happy with my school and me in particular. I was now wanted by the police and the hardest criminal underground gangs that London had.
Our teacher returned to see all of this mayhem and let us say they were none too pleased!!
Finally the luggage came in and the police did not search the luggage (thank god) (tbh they were probably laughing so much they had no energy for the search!!!).
AS you can probably guess that was the end of criminal career and I have never been a big fan of 5th November since. (btw. this must have been in 1970 or so).
Happy days (I am still mentally scared by that day)
