The GED device is, if I remember correctly, 10x more powerful than the SIBIS (what JRC originally used back in the 1980s) in terms of shock delivery. The reason JRC manufactures the GED themselves is because the company that manufactures the SIBIS refused to "upgrade" their device to JRC's "specifications."
Is the FDA aware that JRC puts as many as five (5) electrodes in place per student, making the potential total shock as much as 50x more powerful than the SIBIS? And that JRC also manufactures another device called the GED4, which is 4x more powerful than the original GED, making the potential resultant shock as much as 200x more powerful than the SIBIS?
JRC exhorts their staff NOT to start out with the least effective dose and aim to ramp up, but to start out with the highest allowable dose since it is considered most effective in deterring future misbehaviors...
