I wasn't saying that in jest or exaggerating for dramatic effect. It's simply reality that today, unless you are drunk or high, you can kill someone who is walking in a crosswalk with your vehicle and get away with not even a ticket:
According to the news reports on the case that tweet is about, the police in fact ticketed the driver. A judge dismissed the tickets later, against the recommendation of the police.

Afterwards, police will, as in this case, make up a story how "the little kid broke free from its grandma" and decline to charge.
