If Rondo agreed to do the presser and was with family, during what he considered family time and he doesn't want his family on film, then that should be respected.
Some famous people who like privacy consider their family off limits. They don't want their family members images being put out there. Some consider it a safety risk to their family members; I respect that.
Not everyone is a Kardashian and wants their lives and the lives of their parents, partners, husbands, wives, dates, and children in front of a camera.
Sure, the media is going to give him grief because its their job to film and take photos and ask questions but I think Rondo is justified for doing what he did.
What happened before this instance. Did the reporter ask several times for an interview? Did Rondo several times respond in the negative? Did he stipulate he was with family and didn't want them filmed? Did the camera man then film them anyway against his wishes?
If this stuff happened then I think Rondo 110% justified in his anger towards the man and what he did!!
