maybe potential murderer would get scared by simply police being present nearby?
There was police nearby, like always during such events - surrounding the area of the concert and patrolling the city nearby. The police presence in the city was increased because of the WOŚP finale from 100 to 300 policemen on patrols. The organisers didn't ask for police presence but it was provided anyway out of the police's own will - so was said on Polish TV by some representative of the police in Gdańsk, as far as I remember.
During such events the organiser hires a private security firm which secures the event itself on site, including the stage. WOŚP hired such firm, but it looks like those security guards weren't present at the stage during the attack. The killer was apprehended by... a stage technician who was present at the stage at that time. Before that happened the attacker managed to walk around the stage gesturing triumphantly with a knife in his hand and to deliver an explanation of why he did it through a microphone:
"My name is Stefan W(...). I was sent to prison despite being innocent. I was tortured by Civic Platform. This is why Adamowicz is dead."
Only after that two security guards rushed to the stage and took him away. He was immediately passed to the police even before any call about the attack was made because the police was nearby.
The police will investigate, among others, the behaviour of the security guards during the attack.
I've seen an interview on TV with a former spokeperson of the Warsaw police, who said that he'd been warning for years about the poor quality of the security provided during such events like concerts, football matches, etc. by private security firms. People working there are often random people not trainded for such kind of situations.
I think we have to also keep in mind that such things simply don't happen in Poland, especially not during such events like charity concerts and it caught everyone off guard. That doesn't justify the failings of that security company, though (especially considering all those terrorist attacks in the West). A mayor of a major city was killed in front of cameras and thousands of people, including children, during the most famous charity event in Poland. I imagine that heads will roll.
not even a murder...
Wtf is wrong with you?

One Polish internet user made a following comment: "Jaśkowiak (mayor of Poznań) and the president of Wrocław should get it too... They are becoming the victims of their leftist and Godless attitude towards their public functions."
He's been arrested by the police today, I've heard.
