In the UK at least, PIN-challenges for contactless payment are random. I've heard it's supposedly approx 1 in 10 payments require the PIN, but I've been using contactless payment for just over 6 months, and it hasn't ask

Hypothetically, it should be relatively simple to prevent a power-off-dodges-destructive-action attack, by simply making the operation (incrementing and storing the attempt counter, checking the password) an atomic operation. So they would

It sounds like it has been built that way - the data cannot be decrypted without the correct passphrase - but the user secured the phone with a 4-digit PIN, giving a mere 10,000 possible combinations - easily brute-forceable. The iPhone pre

That's a good point, thanks. I ended up having a look through the differences between detention and arrest (finding different thresholds, e.g. "reasonable suspicion" vs "probable cause"[1], and that "20 minutes

I would hope that the police do have a systematic method of correlating incidents with addresses. Such as, say, a history of reported domestic abuse. Or homes with residents that have been threatened with doxxing or swatting. And informat

There's nothing in the article to say that the residents were arrested. An arrest is the threshold for controlling someone's legitimate actions: if the police don't have enough evidence to arrest the person, then they shouldn

It appears (on the information given) that the police did neither: they didn't lawfully detain the suspects or control their actions through a legally authorized manner (e.g. arrest them, serve a warrant on them), but the police did re

Civilized society depends on well-articulated laws that enable citizens to understand what is legal and what isn't, and allows Police to make use of force when it is appropriate, and prevents them from using force when it isn't. &

This argument seems to be that "The body is mostly water. The task of removing X from water has been well studied. Therefore it's easy to remove X from the body". This seems to be a logical fallacy. Let me rephrase this argum

Just as an example, Bristol to Paddington is 118 miles. 118 * £0.28 = £33.04 for the marginal cost of driving. An anytime ticket is £98.50. An off-peak ticket is £43.00. UK train travel seems to only be cheaper if you can buy an advance tic
