Boston Police Commissioner William Evans joined Boston Public Radio with Jim Braude and Margery Eagan for his monthly segment, "Ask the Commissioner," on Wednesday.

Evans discussed the arrest of Alexander Ciccolo, a 23-year old Adams man who was suspected of plotting an attack on a university. Ciccolo's father, a Boston police officer, was the one who turned in his son to the authorities after suspecting he was interested in fighting for the group known as the Islamic State.

"We all have children, and we hope for the best for them. I also think mental illness is unfortunately in a lot of families, and Bob recognized it in him," he said.

Evans said the incident could serve as a teaching moment to parents everywhere to be well-informed of their children's activities, especially online.

"I hope this is an example for a lot of parents out there: you have to keep a closer watch on your kid. What they're doing on their computers, what they're doing in the basement, whether they have guns on their bureaus," Evans said.

"I like to think this is a teaching moment. If a police captain can turn his own son in and make us aware of things, then everyone should be aware of that," he continued.

On the subject of law enforcement dealing with mental illness, Evans noted the Boston Police have two clinical psychologists who are available to ride along with officers, but that the need for such services is far greater than what two people can handle.

"I wish we had more of them so every station could be equipped," Evans said.
