Militarization of US Police

[Marty]

Minor correction, that's an ASP Baton made from aluminium, it's friction lock operated, normally 24 inches if I remember correctly. 
Also that wasn't CS to my knowledge, that was PAVA, CS has a grey cannister, PAVA is in a red cannister. 

CS spray is a moisture/heat triggered agitant, that forms crystals on contact, acting as an incredibly annoying irritant, that often renders you entirely unable to see or breath clearly. 

PAVA is derived from capsaicin and is a whole lot more effective as you can't build up an immunity to it. 

In terms of the video, it actually demonstrates that a simple metal stick can deter a violent attacker, and firearms aren't always necessary. 
Is this applicable to American policing however? Not really, the climates and cultures are vastly different, our population isn't routinely armed, neither are the police, or the criminal fraternity in terms of using firearms. 
The risk of firearms related homocide is much higher in the US however we can certainly point to a militarisation of the UK police force as well due to current global trends, and the public perception as predicated by the media in the wake of the ''war on terror''.

Scottish Police only use PAVA spray you correct however many cops in Scotland still refer to it as CS, so the general consensus is that’s what it is. 2015 was the rollout of PAVA so really it could be either I don’t the specifics with the canisters etc so you may be correct.

You still here then shouting you’ve been sprayed with CS gas etc etc.

In terms of the baton, it’s correct term would be an ASP baton however again locally we call it a spring baton or in slang a spring cosh, they aren’t however from aluminium. Police issue are definitely steel, carbon steel to be exact.
