If you agree, maybe you're wording was off:
"They can't / won't act on anything that happens outside a stadium, as they're opening themselves up to legal action."

They could, but they won't because their spineless and corrupt *****.
Surely having tons of foreign fans smashing up the city where their team is playing can be considered a football matter? If their team wasn't their, it wouldn't happen. If their home country stopped them traveling, it wouldn't happen.
If that's the point you're making, it doesn't come across well, because that's not what the saying means. You reap what you sow, you don't reap what others sow. So when you say it, you're lumping today's casual fans in with yesteryear's hooligans, and making it sound like they had it coming -...

Russia 2018 shouldn't go ahead.
