The world has moved on with using violence indiscriminately, drugs / alchol violence , gun ,knife use , now acid crime ,and not forgetting terrorism , all have moved to another level of violence , therefore protection should move in tandem to another level .

I would allow tazer use for everyone in a front line job that faces risk even PCSO,s , Paramedics ,A and E security staff (hard to believe we have security personal at Hospitals, that's how low society has dipped ).

Yep arm em and shoot em.
