Gotta disagree with you here. If CrewPass is biometric, there should be ZERO need to screen pilots once through into the gate area, as this pretty much defeats the entire purpose. Let's think about this, the given reason for screening is for security purposes, NOT to catch someone carrying contraband. Security checkpoints have detectors for metal, gunpowder, bomb residue, etc., but nothing for drugs/contraband, as this is not their purpose. A pilot would not need any kind of contraband if terrorism were their motive, they've got a very powerful weapon in their hands already. No amount of random screening is going to solve this, unless they develop random psychological screening on the way to the airplane. Now consider a pilot trying to smuggle contraband, like a shipment of cocaine or something. A security risk? Not really (not explosive or flammable or could be used as a weapon). Illegal? Highly. However, random screening is designed to detect security breaches, not all illegal activity.

Also, random security searches pretty much just applies to employees at airports, not really passengers. TSA hides out near SIDA doors, employee elevators and access points, crew room entrances, etc. But how often do you see TSA stopping random passengers? I can't remember any. Wouldn't one think a passenger might be a bigger threat than a pilot? And if extra screening was required, it lets them know in big capital SSSS letters right on their pass, before they even attempt to enter security! Even more ridiculous is if their boarding pass comes up SSSS at the gate, they are allowed to walk unescorted back to the security checkpoint to get the screening. Gee, ya think any contraband they had wouldn't be hidden somewhere in the terminal area or with somebody else before they attempted to go through the checkpoint?
