In 2009, Gary Olhoeft walked into a Best Buy to buy some DVDs. He walked out with his whole body twitching and convulsing. Olhoeft has a brain implant, tiny bits of microelectronic circuitry that deliver electrical impulses to his motor cortex in order to control the debilitating tremors he suffers as a symptom of Parkinson’s disease. It had been working fine. So, what happened when he passed through those double wide doors into consumer electronics paradise? He thinks the theft-prevention system interfered with his implant and turned it off.

Olhoeft’s experience isn’t unique. According to the Food and Drug Administration’s MAUDE database of medical device reports, over the past five years there have been at least 374 cases where electromagnetic interference was reportedly a factor in an injury involving medical devices including neural implants, pacemakers and insulin pumps. In those reports, people detailed experiencing problems with their devices when going through airport security, using massagers or simply being near electrical sources like microwaves, cordless drills or “church sound boards.”

Sherlock’s record is spotty at best when it comes to engagement. Setting aside the 80,680 people who were ignored by the minister, he was hostile and counter productive to debate from the beginning, going so far as to threaten to pull out of a public debate because a campaigner against the ['Irish SOPA'] SI would be in attendance. His habit of blocking people online who publicly ask him tough yet legitimate questions has earned him the nickname “Sherblock”.
