I've been saying this on this godforsaken forum for YEARSSSSSSSSS. More police are almost never the solution to anything, not only is it costly but it is demonstrably ineffective. Not to mention all of the police on civilian violence that's been occuring in the recent months.
Either way, The best way to combat farebeating isn't to ask the question "how do we stop farebeating," whe should be asking "why are people farebeating" and go from there.
