AA batteries is an interesting choice. Wish we had a ubiquitous lithium-rechargable-based battery standard for products like this that would be smaller than an 18650 but bigger than a coin cell. Design it with some safe chemistry like LiFePo if you have to, but the old 1.2-1.5V AA standard is starting to feel very anachronistic these days.



4 hours seems a bit much, I’ll agree that seems out of line. But I don’t think it’s unreasonable that some questions were asked and he was ultimately approved to enter Canada so it seems like the system, in this case, worked mostly as intended aside from the amount of time it took to reach that conclusion. Canada has had several recent high profile incidents of not adequately vetting extremists entering this country to speak at conferences, and I am not surprised they are carefully screening people in this situation now. While it is tempting to jump to the conclusion that this guy was singled out for supporting Palestine, one isolated incident is not evidence of bias or profiling on any particular issue, there would need to be a consistent pattern established. Maybe there is one and I just haven’t seen it yet, but as far as I know this is an isolated incident so far.
it is a shame that Israel/Palestine has become such a sharply polarizing and divisive issue that we can almost automatically assume that anyone questioning anyone else on the topic is not doing so in good faith and is pushing their own agenda on it, but that’s actually not necessarily the case. Someone can say they’re a Princeton professor and have worked for the UN, but might take some time to actually verify if you’re not traveling with UN and Princeton travel documents, and even that doesn’t prove good intentions anyway. People can have solid credentials in their past, but have changed into something more extreme since then. Unless the person is well-known and already on a list somewhere, you don’t know where the person stands now unless you ask questions and verify answers. Should that have taken 4 hours? Again, probably not, but I don’t think it’s the asking of some of those questions that is the problem here.
That said, if there is going to be a pattern of this, I plan to be watching out for it now. I expect the same process to happen for people coming here to speak in support of the genocide, and I expect them to be refused entry. Will this happen? I don’t know. We’ll see.
