The problem as I see it is that a minority of travellers cause problems particularly after drinking alcohol , but then so do a minority of non travellers.

Comments which neither help, nor clarify. "a minority of travellers" may be as little as 0.1%, or as great as 49.9%.
The same is true for "a minority of Glaswegians".

With such wide terms of reference you cannot (reasonably)claim to be comparing like with like!
