there have been many protests directed at hydraulic fracturing. for example, ten people were arrested in 2013 during an anti-fracking protest near new matamoras, ohio, after they illegally entered a development zone and latched themselves to drilling equipment. in northwest pennsylvania, there was a drive-by shooting at a well site, in which someone shot two rounds of a small-caliber rifle in the direction of a drilling rig, before shouting profanities at the site and fleeing the scene. in washington county, pennsylvania, a contractor working on a gas pipeline found a pipe bomb that had been placed where a pipeline was to be constructed, which local authorities said would have caused a "catastrophe" had they not discovered and detonated it.
