I'm not entirely convinced that you have to "be seen to be doing
something" with a barriered system that requires fare evaders to be
really antisocial to avoid paying


In addition to other comments I'll add that you need to explain then why
there are so many people milling around, most looking exceedingly
unhappy, outside my local Overground station whenever there are
inspectors (invariabl;y accompanied by police) checking entry and exit
at the barriers.
