[Dune] If shields and lasguns don't play well together...

Why didn't Baron Harkonnen just send in an agent with a concealed lasgun to shoot the shield and get rid of every member and servant of House Atreides in one fell swoop? He could then blame this on equipment failure, or on one of the Arrakis citizens unhappy with the change of rule.

Reducing the primary hub of Spice collection and refinement to radioactive glass would not be acceptable to anyone involved in the conspiracy. Even the relatively brief disruption of supply in the time it would take to rebuild somewhere else on Arrakis and reorganize production would cause an empire-wide upheaval, possibly even drawing the ire of the Spacing Guild itself. Remember that Spice withdrawal is lethal, and the Guild Navigators that facilitate interstellar transit require a steady supply to fold space.
