I despise Flock. Have had plenty to say. But I suspect -this- was the reason, moreso than the filming the installation:
> As Keefe began to shoot video, the installer saw him and immediately packed up his equipment and drove away, so Keefe also returned to his car and followed several cars behind, hoping to document the next stop.
Not to say the installer wouldn't have anyway, but it's not inherently unreasonable to call 911 when someone is obviously following you.
So they can film you but you can't film them?
Double standard much?
