Suarez may have done many questionable things, but the handball I honestly can't find an issue with (he wasn't even a LFC player at the time). He broke the rules and got the red card for it, so it's not like he got away with it. If this would've been in the 30th minute of the game no one would've objected.
"May have done questionable things" - quite an understatement! Getting caught and punished for being a cheat doesn't absolve you of being a cheat. As for no one objecting to an intentional handball no matter when it occurs, we'll have to agree to disagree on that.
