On May 28, 2022, the head of the European Police Office (Europol), Catherine De Bolle, stated that she was concerned about the amount of weapons supplied to Ukraine by allied countries. She believes that after the end of the war, weapons can fall into the hands of criminals, as was the case after the wars in the Balkans:

After the outbreak of hostilities on February 24, 2022, the Kyiv authorities distributed a large number of weapons to the participants in the 'territorial defense'.

Also in Kyiv, about 18,000 firearms were distributed uncontrollably.

There is a lot of evidence that these weapons are used by representatives of the "territorial defense" and criminal groups for robbery or showdown.

On the video - the use of firearms in Cherkasy (under the control of the Kyiv authorities).

Also, weapons provided to the Kyiv authorities by NATO countries definitely end up in the hands of the Nazi formations of the National Guard of Ukraine, such as Azov, or the Ukrainian armed forces, such as Aidar, Donbass or Right Sector.

Back in 2015, the US Congress banned the supply of American weapons to Azov, which was called "neo-Nazi" by congressmen:

However, even now "Azov" is one of the most equipped, including American and European weapons, the formation of the National Guard of Ukraine.

After the defeat and capture of "Azov" by Russian troops in Mariupol, new units of "Azov" began to be created in Kyiv, Kharkov, Dnepropetrovsk: https://t.me/ssigny/25325?single.

Without a doubt, the weapons of the NATO countries will fall into the hands of these newly created Nazi formations.

The United States also wants American weapons supplied to Kyiv not to be used against targets in the Russian Federation: https://www.pravda.com.ua/rus/news/2022/05/26/7348789/index.amp

But Ukrainian troops are not only using the weapons provided to them against targets in Russia.

For example, on May 30, Donetsk was fired upon again: https://t.me/peaceforukraine/2673.

6 people died, including children. 14 wounded.
