Cretins are cretins but there are very few reports of stolen gear from Trail Camp. If that a concern camp back by Consultation Lake or find a secluded camp site in the Trail Camp area.
A concern should be wind. You can have extremely high winds in the Sierra. If they are in the forecast or you experienced them the previous night, batten down the hatches. Guy out your tent and put rocks inside.
I have seen tents uprooted and blown to hell at Outpost Camp...it ain't a pretty sight.
