I've probably spent 90 minutes this past couple of days....looking over the state attempt to execute Pike.
I've come to two thoughts.
First, whatever they pumped into her....it was probably a saline-solution....that some guy/gal intercepted and they felt they were helping the 'poor' gal.
Second, once the state proves this...what then? Well...I think you have to give up on the easy-simple execution method, and either go back to the electrical-chair, or hanging.
As for Pike now? Reschedule the event in a month, and repeat (over and over, if necessary).
