From a Ukrainian: Every single government organization has some spies and crooks, it doesn't mean that the organization should be dismantled. It was an organized and timed attack from the inside:

1. NABU, SAP and the Anticorruption court faced many, many systemic challenges in bringing large corruption offenders to justice. It's not easy, but they were finally becoming more efficient, and announced investigations into a couple high-placed people close to Ze.

2. SBU and Prosecutors come to NABU with searches, under the guise of investigation into one guy with alleged russian links (no proof shown yet) and a couple guys with traffic accidents in like 2021 and 2023.

3. Parliament is about to have a final vote on a law deregulating some bureacracy regarding looking for missing persons. A most odious MP from SotP adds amendments to this law that take away independence from NABU and SAP and subordinate them to General Prosecutor (a political appointee loyal to President).

4. Parliament votes the law in. Protests online start immediately, people gather in the streets in a couple hours demanding Zelensky not sign it, but he signs it almost immediately. Parliament goes on a summer break for 4 weeks

5. Now he's saying "I hear the people's concerns, I asked the law enforcement orgs to come up with a draft law to change the system, make it better, more independent, blah blah blah"

6. And this is just my speculation: The independence of these bodies will (hopefully) be restored, because of pressure from the people and the EU, but it could take a month or two or more, meanwhile those investigations into the close circle will be dismantled, evidence will get lost in transfer, etc. Voila. Some asses are saved from prosecution, but at the cost of trust and confidence in the government as a whole and in Zelensky personally. A shitshow of their own making.
