For the record, the local police had to arrive to free the girl from … the federal police.
This is horrific. It’s undeniable that we will need trials for ICE officials and officers after all this.

Cool, cool, so acetaminophen is no longer ok in pregnancy, well we'll just use the *other* drugs on the safe list for pain (haha), fever...ah wait.
Now that we fixed this, can we focus on how paternal age and widening age gaps contribute to risk of ASD?

Perhaps the best irony here, lost on the promoters, is that forensic science actually has really shoddy, mostly non-evidence based, often harmful practices.
The police also is generally a beacon of fairness and justice.

I couldn't agree more w the point that the use of police/crime language abt science is unnerving, counterproductive, divisive. Science does not need an external police force in power. Science can't flourish under authoritarian governments or terms. That's all antithetical to the scientific endeavor.
