Ahh, so now a four year old is responsible for a government employee traveling at such unsafe speeds that either (a) directly striking the child with the bike or (b) bailing from the bike are the officer’s only options.
At what speed was he traveling? What is the posted speed limit? You know these things how? There's no mention about him blowing a light or a stop sign. There's nothing reported about him speeding. Until I see that, I'm convinced they ran out in front of him and left him no time to react except to down the bike or hit the kid.
Offer evidence to the contrary.
