Interesting how "life" is defined by these folks as a "heartbeat" at this point, but "not alive" is measured by brain activity. If you have to terminate a pregnancy at the 20th week, it's usually because there is no (or will be no) brain activity, but women have been forced to carry a non-viable fetus for several days/weeks because it is "alive." These morons should first agree on a definition of "life" that covers the whole span. If a heartbeat (don't even get me started on what that zygote really has at 4 weeks past fertilization) is the definition of alive, then we can stop learning CPR and dispose of all defibrillators. They're already dead, so you just have to call it when the heart stops.
If you pound on someone's chest, or shock them, after their heart stops, then you should be charged with mutilating a corpse.
