A mate of mine has just retired from the Met, he's served in every aspect of their firearms units for over a decade, loved the job, but disheartened by the system, when they charged one of his colleagues with murder, for just doing his job, he nearly handed in his "ticket" along with many others, only thing that stopped him was his impending pension review.
But a lot did quit, & previous applicants that didnt quite make the grade were then reconsidered for fast tracked recruitment to the units, in order to fill the considerable gaps.
With that in mind, I don't think we can say that accidents won't happen, or mistakes be made, a very recent possible was the synagogue attack just a week ago, one of those killed & one of the injured was as a result of police rounds, we've yet to hear the finer details, that probably won't be made public for at least 6 months while every aspect is investigated, the officers involved will downgraded in their duties, & eventually recommendations may be made to prevent a reoccurrence in the future.
My point is, the system takes it very seriously, so much so that should airsoft rifs figure in a police related shooting, the powers that be will have no hesitation in recommending changes in rif ownership, after all we're just a bunch of silly buggers dressing up, & running around playing silly buggers, its highly unlikely that anyone in power will consider that our right to play realistic looking silly buggers will outweigh the need for future public safety or police procedures.
Hence why we've got to be on top of our game, so to speak, & enabling anyone, especially non airsofters to cut corners when it comes to rif ownership, is a massive no no.
If its true, im disappointed that firesupport is accepting cosplay as a defence, they should know better, but money is money in these difficult times i guess ?.
