I tried my hardest not to post, but anyway:
The police searched the accommodation of two SF blokes (one targeted the other simply at this point a co-habitee) and both were found to have some form of illegal weaponry. Quite a lot actually.
There is now anecdotal evidence to suggest that a number of their colleagues had similar items that were given in under an amnesty.
I think it is hard in this situation to explain all this away as a function of the stress, strain and scheduling of their work. A small part of me suspects that a significant number of this unit were simply 'taking the piss'.
