He's got a knack.

Who could stay away?

Joe reminded people that many have lost their sons and daughters.

Joe is the man!

it says that the conversation didn't take place, then or since (or at least hadn't at the time the heckler was interviewed for the article):

The heckler, who calls himself Reinas or “Renas Isis-slayer” in a video explaining why he fought in Syria, said he was still waiting to speak to the vice-president after the incident.

“At first they toyed with the idea of my meeting Biden, but in the end I was told that he didn’t have time for me,” he told the Guardian on Friday. “So I offered my phone number, so that Joe Biden could contact me. I’m still waiting.”

I don't care who the speaker or what the message, it is *NEVER* appropriate to disrupt them. Even if violently offensive. Never.

Maybe I'm wrong, sure wouldn't be the first time. That guy should probably have thought about what he said before he said it. Biden has had as much personal grief as almost anyone, unfortunately.

what do cancer and US foreign policy have in common other than being largely indiscriminate in their killing?

Why that would be the many cancers no doubt caused by the abominable use of depleted uranium in those unfortunate enough to ingest it.
