Kenny is a dimwit, but not as dim as those who voted for him.
He will not do anything about illegally held weapons, inward investment, drugs, raising educational standards etc. The reason is that these are difficult topics with no quick fixes. Even if they can be fixed the solutions are well beyond Kenny's ability. He, like many politicians, has been promoted far beyond his ability or pay grade.
(I recall reading somewhere that the lowest level of gun crime occurs in area with the highest level of legally held weapons, the Northern Constabulary.)
This is cheap publicity for Kenny where he promises a quick fix for a problem (which anyone with a scintilla of common sense will know does not exist) and then takes the credit for solving the non-problem. This justifies his existence.
The reason why Kenny et al are so dangerous is because 95% of the population are halfwits who need protecting from themselves (this is how the government view the populous). And they are more than willing to eat the morsels that they are thrown.
If you do not own a gun or support country sports you are hardly going to be bothered about them being banned now are you?
