If, by a month after the DNC, there is a Wikipedia page about the protests (see links for examples) then this resolves YES.
https://en.wikipedia.org/wiki/1968_Democratic_National_Convention_protests
https://en.wikipedia.org/wiki/2020%E2%80%9321_United_States_election_protests
Blatant Wikipedia manipulation will not cause this market to resolve YES. Needs to be legitimate, obviously.
I will not bet in this market.
For other markets on whether the DNC Protests will be serious, check these out: https://manifold.markets/benshindel/will-there-be-a-death-at-the-2024-d?r=YmVuc2hpbmRlbA

So far, no wiki page. There's a file though, now:
