Apparently a fan jumped the rail last night, but his intention seems to have been to high-five Cena rather than inflict bodily harm.
More seriously, Loss, don't you think those moments highlighted from the past few years touch that kind of heat?
Now granted, that's several instances over 2-3 years and you listed 4 from 97 alone, but I think today's fans can still get nicely riled up when their buttons are pushed correctly.
