Bell techs have done that and caused outages for customers a number of times. One outage ended up costing close to CAD$7900 to repair that they settled for due to it occurring on a weekend in a rural area during a snowstorm that required third party traffic control to meet the Book 7 requirements (on a weekend at the bottom of a hill in a snowstorm with insufficient visibility for us to work safely while doing a road crossing). Normally that would only be a $1k-2k or so, but traffic control, lack of slack due to the location of the cut and overtime for all parties involved really drove costs up. Less than 30 seconds with a pair of wire cutters can be downright brutal to repair if the conditions hit the worst case.
