What evidence supports a finding of a manifest need for restraining defendant during trial?

Here, defendant engaged in multiple instances of violence toward correctional officers dating back to 2012, and as recent as 2016. We conclude that the evidence on the record supports the trial court's determination of a manifest need for restraining defendant. Under these circumstances, we cannot say the trial court abused its discretion -- i.e., acted outside the bounds of reason (see People v. Catlin (2001) 26 Cal.4th 81, 122) -- in finding there was a manifest need for defendant to be restrained during trial.
