Someone comes running for the POTUS, it's a security risk with national security consequences.
What is the likelihood of a streaker at a game actually being a terrorist with murderous intent? Not "is this a non-zero chance of it ever happening?" but "how likely is it it will actually happen"
Well, there's maybe 5-10 of examples in Sri Lanka, Pakistan, Iraq, Maurtiana - but the only western examples are the Boston bombing (11 years ago), the Atlanta Olympics bombing (28 years ago) and the Black September hostages (52 years ago) - and a few IRA bomb threats in the uk in the 80s.
None of these were pitch streakers and this pitch streaker didn't observe any behaviors of the previous MOs. In fact, if they were a bomber, tasing them is probably a bad idea.
I dunno, maybe I'm talking out of my ass here, but I think "fan runs onto pitch could KILL EVERYONE" is a massive over reaction
