In Germany it depends on the path, the police academy includes not only police training but general education (hence why they are called police universities and offer degree programs too) to at least college levels in the US and you may also elect to get your bachelors degree as part of the training.

If you already have a degree your training would be substantially shorter.

While I don’t disagree that the police officer training might need to be reviewed the 4-6 months for the most part is a clickbait that if you look at how most other countries train their police force it’s not that different.

Please note that many police forces in the US require a 2 year college degree / enough credits for one or higher to join the academy in the first place and you have to be 21, countries with much longer “academic” studies for police forces tend to allow people to join the academy at 16-18 and get their 2 years of secondary education as part of their training.

I think the big difference is that most police forces in the US exempt you from this requirement if you have served 2 years or more of active military duty and were honorably discharged.

I presume this is to cut costs. But the logical conclusion of that - giving people a companion app and only 1 month of training - appears very inhumane to me. And it wouldn't be surprising to me if less training with other humans leads to less care for other humans in the field.
