It cannot be said enough, the scientists and technicians should never, ever be collateral damage. They should be the prime targets. Attacking off hours to minimize "collateral" damage makes absolutely no sense. The human capital is the most vulnerable and value part of the whole operation.
Besides, it discourages entrants into the field.
