"Knife crimes are quite popular in the UK, Are their victims less dead than someone who got shot??"

No of course not a murder is a murder. The simple fact though is that there is a far higher murder rate in the US than here in the UK. Hence the odd occassion where you get a poster suggesting that the UK system doesn't protect the citizen doesn't really wash. West Central Scotland is plagued by knife crime. Common sense says it would be much worse if all the neds were running about with guns.
