"White Sunday" (June 14, 2020)
Bethel gained national attention in June 2020, when opposing advocacy groups clashed and Black Lives Matter demonstrators became the victims of acts of violence from the counter-protesters, some carrying guns. The local protest, a part of the larger George Floyd protests, attracted counter-protesters from outside of Bethel, including several motorcycle gangs, Back-the-Blue groups, and Second Amendment advocates. On the day of the protest, 250 motorcycles arrived and occupied the area reserved for the demonstration. In front of local police officers, one Black Lives Matter protester was assaulted. The protester has pressed charges as of Tuesday, June 16, 2020. Counter-protesters were recorded screaming racial slurs at several of the Black Lives Matter demonstrators, including repeated use of the term "nigger". Black Lives Matter demonstrators also had their signs ripped from their hands and torn up by the counter-protesters while local police stood by watching.
