At least in the Netherlands it has been common for hackers to be interested in lockpicking. The irregular magazine Hacktic (which spawned the awesome ISP XS4ALL) used to have features and tutorials about lockpicking.

I assume it is the same for Sweden.

And if you've got a curious mind I cannot imagine why you would not be interested in it!

It's not about being interested in it or not, it's about the appearance. Cops don't know anything about the hacker mind or why they are using them.

Cops aren't hackers. If you're too curious, you can't even be a cop. If I was a cop and I was busting a place doing illegal stuff and I saw lock picking gear laying around everywhere, I would think they are up to no good.

Why everyone here is shocked by thought that cops would think people publicly collaborating to defeat security measures are up to no good is a bit perplexing.

I am not saying they were up to no good. I am saying it is easily believable that they were up to no good. In fact, I would say, cops who did not assume they were up to no good would be remiss in their duties to protect the public, because in most cases, people with that kind of stuff lying around aren't into it for benevolence.

I think you might be misunderstanding what a cutaway lock is. A cutaway lock is a normal lock with portions of the casing made out of transparent material or removed entirely. Their specific function is to practice lock picking. And blank keys aren't tools with a single usage scenario. Good guys and criminals alike use them to copy or make keys. The important thing here is not to judge by the equipment, but by the intent of the owner. Most laws about owning lock picks reflect this pragmatic view.

Also, if you're attempting to criticize the activity of lock picking in general, realize that it is a long standing tradition in the hacker community. Sergey Brin is a prominent example of a "non-evil" person who tinkered with it [1].

Local, state, federal, and whatever other applicable laws permitting, you should definitely learn to open easy locks with paper clips (optionally a pair of pliers and a screwdriver as well). We did it on the last day of the graduate-level security course I took, and I will definitely never take the security of locks for granted again.

They have their use, they ensure that only sophisticated thief get away with your loot. Makes for more impressive local news coverage than this http://www.youtube.com/watch?v=wQqk-x7dD0Abest quote is at 1:40. Skilled practice a throwing bricks.

Purchasing and using a bump key (http://en.wikipedia.org/wiki/Lock_bumping) is not particularly sophisticated.

I don't think that's fishy, it sounds like normal hackerdom to me. I have a nice set of lock picks and have enjoyed messing around with opening locks for years and years. For me, it's a perfectly normal part of exploring the man-made world.
