Last year it was no lasers, this year it's also no soldering. This is how hacker cons die. #34c3pic.twitter.com/n8Ep3BQ6Px

It wasn't a problem every year prior, then suddenly all lasers disappeared on day 1 of 33c3. Whatever the problem was, it had nothing to do with individual lasers and everything to do with some kind of general decision, legal or otherwise.
Note that "is something illegal" is rarely a valid blanket argument. I'm sure countless German rules and regulations are broken at CCC each year and nobody cares.
Actually there's nothing "illegal" about operating high powered lasers. The problem is, that if something bad^TM happens the rules on liability and insurance can create a HUGE backlash on events like the C3.
Huh, actually on the 33c3 in the upper levels of the CCH there were a few high powered lasers, with a static beam configuration, also leaving the premises, which made me kind of nervous. If you can see a red laser beam without fog it's certainly beyond class-3a
Laser classes are useless. The danger posed by a laser is way more complicated than what class it is. Any useful scanner is going to be Class 4 (mine is), but there's a huge difference between a laser pointer (static beam) and a scanner at a minimum distance.
