There are criteria is what I am saying. I would agree with pulling people off the street so their status can be checked. Might not produce a bigger jury pool but would help identify those here illegally. Those unable to produce proof of identity may be liable to being detained while the check is carried out. No nonsense of reporting with your documents in two weeks time etc. Miscreants would be taken from street to deportation facility, possibly allowed to collect some personal effects if securely accompanied and if they give up details of if they were working, where it was and who employed them etc. If not, it's the clothes you were wearing at the time. Phone subject to investigation etc etc. No privacy bs , where there is a question of age then medical tests to determine age at will of the authorities. DNA swabbed and biodata entered into facial and gait recognition system.
