Do you think chauvin should testify in his own defense. Why or why not?

Not at all, he has a constitutional right not to. It's his choice. He made it. 

The Fifth Amendment says a defendant may choose not to incriminate himself in questioning.  But it's different in court.  He may decide not to testify at all, but if he does testify, then he must answer every question put to him.  He can't be selective.  He can't say 'I take the fifth on that question'.  This is the reason a lot of defendants decide not to testify.

I was on a jury years ago, a fairly complicated trial that lasted 7 weeks.  There were three defendants, two of which didn't testify.  I tried not to hold it against them (as we were instructed by the judge), but several of my fellow jurors thought these two guys must have had something to hide.  So it looks bad not to testify.

Im nowhere close to a legal expert, but isn't it common for the accused to not testify? I don't see how he could help his own case by taking the stand.

Obviously the prosecutor would have asked him "did you hear Floyd say he can't breathe?" and no possible answer from Chauvin could have helped him. 

It's a risky move. He'd be cross examined by a prosecutor with a lifetime of experience. One mistake could hurt his case terribly. Sometimes it's better just to let your lawyer do all the talking.

No.  No reason to do so.  Doing that helps the prosecution more than the defense, which has adequately shown the prosecution hasn't proven their case beyond a reasonable doubt.

I think Chauvin and his Lawyer are much better informed than anyone on Y!A on this matter 

Doesn't matter. He already took the 5th. 

What I think is irrelevant.  It's what his lawyer thinks that counts.

I think he should not testify.  The facts in the case are clearly known.  Anything he says can be used against him.
