Witnesses say he was "chewing on batteries" before the incident.<p>Must I now worry that the Chinese are putting fentanyl in my batteries? Must I consider the possibility of being mugged by a "battery-chewer" (ChewBAAAca?). Will there be a run on batteries at the supermarket? Should I buy more batteries now, avoid the run and risk being labelled by my supermarket as a drug dealer/user?<p>This goes beyond the pale. Give me back my landline.
