Not sure what you mean. The name "Yantis" is generally a German or Dutch name, although anyone can "adopt" a name.
Hadn't seen that rumor, that foreigners are involved. If they are, it stands to reason that don't know how the government in the States works.
My guess about what happened is, the cops were having fun shooting at a dying bull. The bull belonged to Yantis, who was there to put it out of its misery. The cops probably ordered Yantis to not kill the bull, because they wanted to have some more "target practice" fun. When Yantis didn't obey, one of the cops became confrontational by grabing Yantis' rifle. The rifle accidentally discharged, the second cop panicked and started shooting at Yantis, the first cop became mixed up and joined his buddy cop, and since he was at point blank range, simply did not miss when he shot at Yantis.
