In far too many cases, the cost of fighting even frivolous litigation means that it is cheaper for targeted deep pockets to settle than to fight and win. Some form of loser pay is desperately needed in far more cases.
Had this suit been mounted by a couple of gun owners who disarmed in accordance with the posted theater policy, I'd be much more sympathetic to the victims.
Heck, if the basis of this suit were that by posting a gun free zone the theater had created a dangerous environment that attracted criminals, I'd also like to see the suit succeed. I haven't read the suit so if this was the basis, I'm sad to see it fail.
But if 4 dozen money grubbers decide that someone else is responsible for their safety and they are entitled to retire because something bad happened, I'm less inclined to go along.
