Former Red berets, whose members were convicted for the murder of Zoran Đinđić, employees of Serbian institutions in Kosovo, members of the Serbian Progressive Party from Niš...
All these groups have one thing in common - they started to gather in Pionirski Park around the ćaci, that is "Students who want to learn". They have another group characteristic - probably no one has a student index, at least not a current one, judging by their years of life.
And that might be valid. Like-minded people came to support the common cause, to support Aleksandar Vučuć under his windows on Andrić's venc, spend the night and hang out with his friends.
Just so that everything does not point to a calculated provocation that has a great potential to turn into a conflict.

Why is Pionirski Park full?
In an interview with Informer on the evening of March 11, the President of Serbia said that he received the students' plan to block RTS from the Udba "10, 11 or 12 days ago."
About the whole plan, under the symbolic name "15. for 15″, "Time" was already written, after Vučić talked about some more of his details during his guest appearance on RTS on Monday, March 10.
"They will start from four directions: from Trg Republike, Novi Belgrade, Autokomanda, but it is not yet certain for the Faculty of Forestry," said the president during an appearance on the Public Service.
The plan of the students in the blockade also states that the central event of the large protest on March 15 will be in front of the Serbian Parliament, as well as that it is planned to fill the space next to the Presidency of Serbia, where Pioneer Park is located.
If Vučić received the plan 12 days ago, it means that he knew about it already on February 28 or March 1, so he had time to mobilize "students who want to study and other loyalists of the progressive government" and position them in Pioneer Park. The children arrived in this park with the same tents, the same heaters and the same desire to learn – March 6th.
Who is sending the threats?
Vučić said on Informer television that "he will do his best to preserve peace." And already in the next sentence he said:
"The state will have to defend itself." We will arrest every thug who wants to destroy the country. I am proud to be on the side of truth and justice, and against plenums and assemblies. I am sure that Serbia will win. They will be very aggressive on Saturday, but on March 15, the countries will play the end," said Vučić, and Informer reported this statement with the explanation that "this is the central message" of the country's president.
The head of state also said that "the state will show its strength", adding that four people with phantoms broke into Pionirski Park and were arrested.
"I tell you in advance, you will see that at least two of them have already been arrested as drug dealers or as Sholak's employees," he said.
FDU students sent a statement in which they responded.
"We don't make a mess, you do." We are not calling for violence, you are. We are not violent, you are. We are not paid, you are," stated FDU students with clips broadcasting violence against students and speeches of SNS officials who called for violence in the previous period.
Who all gathers in Pioneer Park
Veterans of the Special Operations Unit (SSO) came to Pionirski Park on March 11 to support "Students who want to learn". About 70 red berets were seen that day, and some of them set up their own tents as support for the counter-blockaders.
Videos of military tents appeared on social networks, and one of the men in uniform can be seen threatening the citizens on the other side of the fence with "we will beat you", and then he runs and hits the hand of a younger man who was filming them with a phone. In question is Živojin Ivanović, aka Zika Crnogorac, who some claim was the first commander of the "Red Berets" after Captain Dragan.
In September of last year, he was filmed with the Vice President of the Government of Vojvodina, Sandra Božić, who visited the "Association of Veterans of the Red Berets" stand at the Assembly of "Krajišniks and Friends" in Kovilov, reports N1.
At the head of the column of veterans who came among the students of 2.0. there was also Goran Radosavljević Guri, retired police colonel and former commander of Special Police Units and first commander of the Gendarmerie.
People from Kosovo who need work
The same day the video appeared, transmitted by Media Center Čaglavica, which shows a group of young men from the municipality of Gračanica arriving at the Pioneer Park in Belgrade.
However, as can be seen from the available information, there are almost no students among these young men, but rather people employed in Kosovo and Serbian institutions in Kosovo, the media center adds.
Among the men who came to Belgrade, there are mostly employees in Serbian institutions, but also those who are not permanently employed, writes the Radio Kim portal.
Not only the residents of Gračanica and Laplje Selo went to Belgrade, but, as Radio Kim unofficially learns, also from Kusac, Zubina Potok, Mitrovica, Štrpce. Most of them, this portal writes, leave with their own transport or vans.
Niš invites youth under the age of 31
Numerous members of SNS from Niš also went to the park in the center of Belgrade Southern news writes how "Niš SNS recruits from its ranks those who go to Belgrade, where they join - 'Students who want to study', although many of them are not students".
In the Viber group of Nis progressives, "all young people under the age of 31 are invited to contact Luka", and Luka, according to Južni Vesti, is the deputy mayor Luka Gašević.
