Lake County sheriff's testimony called into question

The Lake County district attorney has determined Sheriff Frank Rivero lied during a 2008 investigation and therefore must be on a list of law enforcement officers whose court testimony may be questionable.

District Attorney Don Anderson said in a report that Rivero "did not tell the truth and made material misrepresentations" after a 2008 confrontation when Rivero shot at but did not hit a potentially violent man holding pepper spray.

The finding means that Rivero is now tagged as a so-called "Brady officer," a term stemming from the U.S. Supreme Court's 1963 Brady vs. Maryland decision that said the defense must be told when an officer has a history of making false statements.

Rivero took the unusual step of challenging the district attorney's finding in a civil suit filed Feb. 28, claiming that the investigation into his statements was unfair and violated his due process rights.

"Allegations against my credibility are absolutely damaging, but they're not true," Rivero said.

Prosecutors must now weigh how crucial material testimony from Rivero is to a case, Anderson said.

"When it comes to putting on a trial and evaluating a case, we will have to ask, 'Is it a case worth going forward with? What's a jury going to think?' " Anderson said.

Anderson's decision to put Rivero on the Brady list came to light Monday during a public hearing when a judge denied Rivero's request that the documents be kept under seal while he challenges the report.

Judge William Lamb said that it's in the public interest to have the facts regarding an elected official emerge in open court.

The decision prompted the immediate release of Anderson's report, finished last month, that outlines conflicting statements from Rivero about whether he saw pepper spray in a man's hand and how the man moved before he fired one shot.
