>He isn't just a politician with ties to mafia, he is a politician emerging from mafia. That's different for countries outside Africa and Latin America.
He was from KGB. Telling that KGB is a mafia is far fetched.
And lets go to your cases:
https://en.wikipedia.org/wiki/NTV_(Russia)#Talk_show_with_people_of_Ryazan_and_FSB_members
This case is not clear for me. Some guys in government threatened NTV for bombings reports.
https://en.wikipedia.org/wiki/Beslan_school_siege#Storming_by_Russian_forces
Russians special forces doing badly in hostage saving situation is not new to me. But hostage operation is one thing and assasination attempt is another.

The whole case is shady I have to agree. Especially I was concerned how jirinovsky was shut during his speech. Later he told to that zoomer reporter that he denies the idea that intelligence agencies were behind it and said that there could be some mistake. Believe him or not is up to you.
https://en.wikipedia.org/wiki/Kursk_submarine_disaster
Kursk submarine was a mess I agree on that. It was a tragedy and they valued their secrets more than soldier lives.
I can even bring more cases. The last horrible disaster was in cemerevo where all was shitty prepared and shitty implemented. So many children died in fire and that fat annoying cunt in charge just left his position instead of further prosecution.
But still look. I will try to explain.
The version which is promoted by western propaganda is that putin killed a leader of opposition with novichok poison.
First of all, so called novichok failed with skripal assasination. Which is btw another case which ended up nowhere. And west likes to tie those cases assuming that putin actually poisoned scripals. And this version already falls appart since it makes no sense to use poison that failed once alredy. Besides there is many more easier ways to kill a person and even make look it like an accident. There is no point for such a james bond circus with horses they try to portray.
Secondly what are motives behind it?
How long is Navalny around? And Putin tolerated him all that time. More over in some latest elections he proved himeslf being some selfish populist not different than putin. I don't like peskov but he made a good point that navalny is so incompetent he could not unite opposition. Out of nowhere he becomes a threat to Putin so Putin poisons him. I just don't see any trigger that made him suddenly want to poison Navalny. If you could tell me something then it would be nice. I maybe miss something since I didn't follow navalny for long time due the fact how he keeps discrediting himself.
And finally, why send evidence?
Why would Putin want to give Navalny to the west where they could find any information against him? If I am a criminal and I commited a crime, then it is in my interest to avoid others to know that I did it therefore my actions would be hidding evidence no revealing it to other parties.
You can blame Putin creating such situation that he is considered the least evil by Russians and that whole opposition is just a bunch of clowns who are not reliable and could not be treated seriously. But that he somehow tried to assassinate Navalny is very unlikely because Navalnyi is no different from those clowns.
For now, the only way in which I would consider government somehow involved in all this case is that if Navalny somehow discovered something that would turn upside down everything.
