They also don't publicise everything they know to keep criminals from knowing everything that can be tracked. There was a huge case in Switzerland a few years ago. Quadruple murder, horrific. The police caught the guy (unknown to the family but living in the area) after a few months. They have never revealed how they found him, not even during the trial. They said they cannot reveal it because they don't want other criminals to avoid detection.
Exactlty, I remember there was a terrorist attack in France years ago where hostages were taken in a supermarket and one of the police officers pulled a trick where he exchanged himself for a hostage and had his phone on a call in his pocket so his colleagues could get the information they needed. The media afterwards screamed 'HERO COP OUTWITS TERRORISTS WITH PHONE' and all I thought is that'll never be able to save people's lives again now.
It's worth bearing in mind the sources for all the information in this case. The only reliable source at the moment I would argue is the police, although they may be omitting some information for their own reasons. Be exceptionally wary about tabloids and social media posts. Most social media posters (twitter/tik tok) are trying to get clout or validation on the back of it. The standard for journalism has declined horrendously and many outlets, even known names, don't double check information with multiple sources because it is a race for clicks in the nonstop 24/7 news cycle.
People have likened the wider behaviour of the public to Black Mirror but for me it is also reminiscent of Jake Gyllenhaal's amazing performance in Nightcrawler: Lou Bloom is a sociopath looking to capitalise on the unregulated way the news gets it's clips, and if it bleeds it leads - regardless of the ethical issues. Except instead of one Lou Bloom the village has been descended on by dozens.
