Kids are different. An innocent person would have no reason to flee law enforcement.
Fleeing law enforcement is defiance of the law.
So the death penalty includes failure to stop.... like Cuba, or Nazi Germany.
These border cops were found by the jury to have lied and destroyed evidence, so I will turn it back to you: An innocent cop has no reason to lie or destroy evidence.
And really, the argument is a slippery slope even beyond that. For example, one could say with equal validity that an innocent person would have no reason to fear unannounced warrantless searches of their homes and property. Or that an innocent person would have no reason to fear tracking devices and speed monitors being put into every automobile.
