Getting back to countries. No it is not getting more insecure. For example in Germany, there is a clear tendency of decreasing murders since 2000, with smaller ups and downs from year to year. But the trend towards less murder seems undeniable:

France has also a macrotrend to decreasing crime rates while small sluctuations are taking place over the years.

Same with Switzerland:

Spain as well:

Italy the same:

In Sweden most types of crime increased a little since 2013, only theft rate dropped by 11%:

And also the trend in Sweden seems to be increasing:

But Sweden seems to be a anomaly outlier in Europe, since all other countries I searched crime rates are decreasing.

UK seems to be quiet stable without clear trend of increase or decrease over the decades:

So much to the past of the last decades, to me it seems europe improved a lot.
