Was Brown v. Board of Education the most important event in breaking down the legal foundations of the Jim Crow system?

I want to argue yes, but I can't think of anything creative, only things that are obvious. Any ideas?

This case, that "separate but equal" could never be equal, proved that segretated public facilities was unconstitutional. It aroused the public passion and encouraged blacks to try to enroll in white schools. That brought on the murders, a governor standing in a school doorway, and police with firs hoses and dogs. TV coverage of these brutalities dynamically caught the attention of the nation -- and thus -- the Jim Crow system was dismantled.
