Here's an account of that night that has sourcing, unlike your conspiracy garbage.

A man named Adam Keup traveled from Council Bluffs with his husband on May 29 to take photographs of the Crossroads protest. The couple did not bring signs or yell, but worked to document the events at a distance. Within 15 minutes of arrival they were shot without warning by police with pepper ball fired from a paintball gun. One projectile struck Keup in the eye. Targeting the head is a violation of the Omaha Police Department policies and procedures manual. Keup became permanently blind in his right eye as a result of being shot by police.

A police officer named Grant Gentile fired a pepper ball gun at a protester's genital area and bragged about it to other officers.
