Defense Attorney Mike Cavalluzzi Says Crumbley Verdicts Might Help Parents

Ethan Crumbley's parents have been convicted of involuntary manslaughter in connection with the crime committed by their son ... an outcome at least one criminal defense attorney sees as both a troubling sign and a great lesson for parents.

We spoke with attorney Mike Cavalluzzi -- a Los Angeles-based lawyer -- about the verdicts on "TMZ Live" Friday, and, while he said he's concerned about the expanding criminal liability ... he's also seeing it as a wake-up call for parents.

As Mike explains it, school shootings in the United States have become far too commonplace, and he says he views verdicts like this as a way to stop people from buying weapons these shooters end up using to harm others.

Mike also called the potential changes parents will make from Thursday's verdict opportunities rather than consequences -- as in, giving people the opportunity to make good parenting decisions.

Basically, MC says the verdicts will likely keep parents on high alert ... and, hopefully, that will help parents see the warning signs before it's too late.

As you know ... Ethan Crumbley -- who killed four students during a 2021 shooting at Oxford High School in Michigan -- received life without the possibility of parole back in December, but his parents were also charged in connection with the crime.

Ethan's parents -- James and Jennifer Cumbley -- were both found guilty of involuntary manslaughter for being criminally negligent in the lead-up to their son's shooting ... with prosecutors even claiming James bought Ethan the gun he used days prior.

Jennifer was found guilty in early February while James got his guilty verdict Thursday ... but both are scheduled to be sentenced April 9.
