you have to have some sympathy for US police. They're constantly in fear of getting shot or knifed.
Unlike British Police they fire first.
So why Trump said British police feared for their lives, I have no idea.
Maybe just another bit of his BS.
Met blasts Donald Trump for 'London police in fear' claim | US news | The Guardian
Firearm-related death rate per 100,000 population per year
UK (2011) 0.06
France (2012) 0.21
US (2013) 3.55
London 1.4
Paris 4.4
Washington 15.9
Chicago 19.4
Don't blame the police for being scared. Blame politicians for making sire they are scared.
