• Hacker News1Ousted Savannah police officer gave ICE agent husband access to Flock systemSavannah police fired Amber Harpe after she gave her ICE agent husband her Flock license plate reader login, which he used for about 983 searches tied to ICE targets. Her termination was upheld and her appeal was withdrawn.Law enforcement abuse of surveillance tools:Commenters argue every surveillance tool given to police gets abused, that officials naively assume officers will follow rules, and that a Flock officer sharing her login with her DHS agent husband shows the problem.Weak access controls for sensitive systems:Many were surprised Flock uses basic username and password login accessible from anywhere. Commenters noted that health and corporate systems typically restrict access through IP allowlists, VPNs, device certificates, and MDM.Accountability and legal consequences:Users question whether credential sharing violates the CFAA and should be prosecuted, but doubt charges will come since ICE and federal officials are seen as above the law. Chatrie v. US may affect Flock warrant rules.
• Reddit science1A clinical trial has found that hydrodissection, injecting saline to separate a trapped nerve from surrounding tissue, provides carpal tunnel relief lasting up to 6 months, outperforming standard steroid injections.Saline injections around the trapped nerve in carpal tunnel syndrome, a procedure called hydrodissection, appear to relieve symptoms longer than steroid injections. In a small trial of 63 wrists, relief lasted six months, while steroid-only benefits faded. Larger studies are needed.Terminology and mechanism:Commenters debate whether "hydrodissection" is a misleading name, and one clinician explains it separates the nerve from surrounding tissue using hydrostatic pressure, unlike hydrodilatation in frozen shoulder.Surgery versus injections:Many argue carpal tunnel release surgery is quick, low-risk, and highly effective, so repeated injections or alternatives may only delay it, though some note complications and access barriers.Use for other conditions:Users ask about trigger finger, tarsal tunnel, sciatica, back, and other nerve problems, but one reply says trigger finger is an inflammation issue, so the technique is unlikely to help it.
