Makes sense - from ABC News (caution: obnoxious loud self-loading video at the site):
'Domestic' terrorists could target July 4 holiday events, but no known plots: Feds
Federal authorities are warning that white supremacists and other political radicals could look to attack Independence Day revelers on July 4, noting in a bulletin to law enforcement around the country that domestic terrorists “have attacked perceived oppressors, opponents, or enemies engaged in outdoor First Amendment-protected rallies or protests during past summers.”
Practice good situational awareness, avoid large crowds, don't travel. Basic common sense.
I think Sasquatch populations might outnumber the hysterically inflated supremacist threat. Media aggressively fans the flames of everything you cannot see or quantify to generate a threat. The opportunist politicians jump to save us from these imaginary concoctions. Rarely does the threat meet the hype.
