Two separate issues here though:
1) A subset of Liverpool fans being cunts, which letís be honest every team has some of and isnít going to change. Identify the individual, ban/charge them and move on.
2) Ridiculous heavy handed policing by Spanish police, something which happens year after year and nothing ever gets done about it.
Iíll be the first to claim that their fans are more ludicrous than any others, and there is some weird cult mindset about how they deserve everything. They arenít more violent than any others though, every club has itís dark incidents in history and a minority of wankers.
