This incident was prompted by archways erected in the city of Baldwin Park that have murals and inscriptions on their arches which are considered by some folks to be anti-American if not downright treasonous. Sayings like, "Things were better before they came." and "This land once belonged to Mexico and the Indians, and it will again!" Same old Mecha and Aztlan BS claiming ownership over all of the southwestern United States by Mexico. Land which was "stolen" from them. As I recall, it was ceded by the Mexicans in the Treaty of Guadalupe Hidalgo circa 1842 (correct me if I'm wrong here folks) following war with the big bad white European blue eyed ugly mean devil worshiping thieving "settlers". You know the ones. The guys who set up farms and built roads, businesses, schools, and churches. The ones who civilized a savage land thereby ending the savagery.
Some anti-illegal immigrant folks were protesting this "artwork" and were spat upon, cursed, and otherwised demeaned by those attending who found the "artwork" to their liking. This is what the racist left calls "dialogue". Anyway, a 66 year old gray haired female anti-illegal immigrant "protester" was hit in the head by a water bottle, presumably full, thrown by one of those promoting "dialogue". She was hospitalized and released, but has since been seen by medical personnel again. Her injuries appear to be greater than first assumed. More to come on this matter, I am sure.
