Jack Montgomery writes at Breitbart:

Four people have been shot over a 48-hour period in Sadiq Khan's London, leaving a teenager dead and a 13-year-old and a 15-year-old with head injuries. . . .

The shootings came as establishment politicians and commentators were working themselves into a lather over comments by U.S. President Donald Trump concerning the level of violence in London, delivered at a conference of the National Rifle Association (NRA), which defends and promotes Americans' constitutional right to keep and bear arms.

Surgeons at a London hospital which President Trump compared to a "war zone" admitted he was right about knife crime in the British capital, but argued that guns were "no solution" to the problem, and that gunshot wounds were more difficult to repair than knife wounds.

"The doctors appeared not to understand that President Trump was not advocating for criminals using knives to be given guns instead, but for law-abiding citizens to be allowed to own arms for self-defence," Montgomery observes.

"In any event," Montgomery concludes, "the wave of shootings over the past weekend, viewed alongside statistics showing gun crime in London rose by an astonishing 42 per cent from 2015/16 to 2016/17, would appear to suggest that limiting legal access to firearms for ordinary citizens does not deter criminals from using them.
