....the vest and/or cut proof clothing is a no brainer.......of course....proper use of handcuffs and restraint techiques might have helped prevent that tragedy too.
That appears to be an over simplification of what may have happened in Manchester... they went to a 'breeze' and all of a sudden it seems to have turned serious on them.
In most instances that sort of scenrio would have resulted in body armour being left behind anyway. Personal issue handcuffs? Well they are a new invention anyway and the same applies! Any automatic handcuffing in the Uk is a very recent development ... if there was no violence offered at a 'breeze' type scenario there would be little reason to use them. ... although that it slowly changing as officers wise up ...
Thats life I am afraid.
