Police Spit Hoods For Violent Arrests?

One third of police forces use 'spit hoods' to prevent violent arrestees from spitting in officers' faces. Apparently, according to leftists and 'human rights activists' - this is unacceptable and cuts across the 'rights' of violent scum.

Why are the rights of police officers of no import to these wretched people? - Our protectors are not the ones in the wrong! This makes me so very angry!
Today, to be a leftie - you really must be psychologically damaged. It is not possible for these people to be so very wrong on so very many issues.
The damage they continue to do to our society is almost beyond measure!
