In the comments, a Twitter user asked how we responded to his son’s question.
Swalwell replied: “I told him he is going to be OK and he shouldn’t worry. Which is a total lie. He lives in a country of unrestricted weaponry.”
Someone else commented: “Your young son is one of many asking questions. The horror they are growing up with is unacceptable.
“I know you're doing all you can to turn this around.”
Another said: “My 4yr old is asking questions here tonight. He wasn't born yet, but knows he has a cousin who's in heaven.
“We lost our 6yr old nephew at Sandy Hook so we know the ache that entire community is feeling and there are yet again young children asking why as we parents weep.”
One person wrote: “I'm so very sorry. No, child should have to even think about these things.”Have your say in our news democracy. Click the upvote icon at the top of the page to help raise this article through the indy100 rankings.
