you know why... because they know Wells did not do this (they are covering their butts for not listening to him or they are screwing with the real person who did it... notice how they keep pointing out Wells was slow, a high school drop out, blah blah blah but still are claiming they don't know if he did this to himself or not. After reading this morning about the locks and that they most likely came from Brazil (sold here through American Distrubutors under their own brand name) I knew that it had to be someone that had knowledge of what these types of locks are used for.

Perhaps, but it is possible that whoever made it just had access to them out of happenstance - found them at work, or on a scrapped machine, etc. It is not difficult to design something like this. I would guess any nutjob with some basic shop skills and electrical knowledge could pull it off. Take a look at the metal housing for the lock/timer assembly and notice the crude construction. The steel was machined with hacksaws and files and one of the screws is missing because the bolt holes do not line up - although it could have been damaged from the explosion. The collar assembly looks like it was from something else and welded to the timer/lock. It looks too complex for somebody to make with the same tools (hacksaws and files) that were used for the timer/lock. It also looks too complex for the purpose.

either they are high security cargo locks or they are switch locks...I cannot not tell as I cannot make out the keyhole in picture well enough.
