Tucson's police chief is appealing to residents to give his department time to fully probe Saturday night's clash between fans and police after the University of Arizona basketball team's loss to Wisconsin in the NCAA tournament.
Roberto Villaseñor called it "a difficult situation," and not one "where judgment may be made lightly or without knowing all the facts."
Here is his complete statement posted on Facebook:
"While I understand the level of emotion concerning videos that have been circulating from March 29, I would like to implore members of the community to allow us the time to thoroughly investigate the incident. I am not making any excuses; however, I am duty bound to weigh all of the evidence in this situation, which necessarily involves consideration of differing perspectives, statements and viewpoints. This is not the type of situation where judgment may be made lightly or without knowing all the facts. If our conduct was wrong, we will hold ourselves accountable.
"These are difficult situations that often put law enforcement in a no-win situation. On the night of Thursday, March 27, the Sweet 16, we did not deploy additional resources in the area, and we had to draw resources from across the city to deal with the hundreds of people that took over University Blvd. Even though we had never experienced that type of crowd reaction so early in the tournament, there were some questions as to why we were not ready and deployed. So for the Elite 8 on Saturday, we did deploy additional resources based upon what happened two nights earlier and are now questioned as to whether our presence was the cause for the disturbance.
"It is important to acknowledge that there were numerous people present on Saturday night who came out expressly for the purpose of causing a disturbance. Social media sources of comments posted before and during the event prove that. The fact that there were no serious injuries and only one bent street sign demonstrates that our presence helped maintain control.
"We are not an organization that shies away from being self-critical and holding ourselves accountable. It is easy to paint with a broad brush in situations such as this, but again I am asking the public for a little patience while we take the time to conduct a thorough investigation and arrive at fact supported conclusion.
"As for comments on this site, we reserve the right to delete any vulgar or profane language, but we will no longer restrict critical postings concerning our actions. We understand that as part of government, we are responsible to you, the citizens, and your viewpoints are important."
Tucson police said most of those arrested were current University of Arizona students.
Police said 15 people were arrested during what police called an unlawful assembly just outside the university campus after the Wildcats lost to Wisconsin.
University officials were vowing to punish students who participated in the fracas.
Dean of Students Kendal Washington White called the disturbance disappointing and said it was not reflective of the culture of the University of Arizona or Tucson.
Authorities said fans hurled beer bottles and firecrackers at officers, who then used pepper spray to disperse the crowd.
The ages of the people arrested range from 19 to 29 years old.
No officers or fans were injured in the unrest that lasted more than an hour.
Meanwhile, the Police Department said it is reviewing cellphone video that appears to show a woman being shoved onto a bench as she walked past officers during the disturbance.
In 2001, police arrested 17 people after Arizona lost to Duke in the national championship.
