I have been on juries twice and I think there is a lot of room for improvement. In one case there was an expert witness that made claims about light during dusk which i was pretty sure was questionable based on my photography experience. But there is no way to challenge such statements if the defense lawyer doesn’t do it and even then it probably costs a lot of money to find an opposing expert witness. Most defendants won’t have that money.

As a juror you are supposed to judge only by what has been presented in court. But this leaves a lot of room for bullshit experts.

I think there need to be some nationwide standards about accuracy of different methods like alcohol tests, speed traps and especially forensics where I have read that a lot of completely false methods are being used to convict people. The judge should have the ability to call out such things based on established scientific evidence and inform the jury.

I'm pretty sure a judge can call an expert witness's bullshit, but that requires a judge to be an equal expert in that field, which is a terribly high standard.
