Welcome to Pepper Spray Nation. America's newly favorite weapon is making its way from the streets of California to the aisles of Walmart to the country's high schools. DNAInfo reports that nine Harlem students were rushed to a NYC hospital yesterday afternoon after a 14-year-old used pepper spray in a classroom. The Academy for Social Action didn't comment on why the girl blasted the spray, notes the New York Daily News. A student tells the Post that the classmate "sprayed the irritant indiscriminately into the air."
