Stadiums can ban a fan for life. But they can’t easily enforce it

( CNN) It’s been an disturbing week for players and fans alike at Boston’s Fenway Park, where baseball games were defaced by two racist incidents.

On Monday, a Baltimore Orioles player mentioned fans shed a handbag of peanuts at him and razzed him with ethnic monikers. The next darknes, a fan was exhausted after placing a ethnic insinuation at another love nearby.

The Boston Red Sox answered quickly and forcefully, publishing confessions and telling the offending love he is “no longer welcome” at the ballpark.
