Part of the problem these days is very few have proven themselves to have integrity and trustworthiness. Much of the mainstream media has proven themselves to be untrustworthy over and over again
Main Stream Media is not really a thing.
You have various Media companies, they aren't necessarily tied together.
Typically media outlets have journalism, opinion pieces,
The journalism side is high on news and facts (typically)
The opinion pieces are high on opinions and persuasion and sometimes manipulation, and perhaps lies.
For example, a piece of journalism would report that the FBI is investigating whether members of Trump's 2016 presidential campaign were collaborating with the Russians in their attempts to interfere in the 2016 USA presidential election.
Or a journalist might report that the FBI have raided Maralago in search for confidential documents.
An opinion show might muse that the FBI are trying to influence the mid term elections, might muse that Marrick Garland has a grudge against Trump <for whatever reason>
Journalists are more culpable with regards to defamation, whereas some opinion show hosts (Tucker Carlson) have successfully argued in court that people don't expect to get the truth from him
So if you are looking for factual information you should seek out journalism rather than opinion shows.
And then rather than worry about the media company, you should note down the key points or claims made, and then do your own research. See if other media outlets are saying the same points or claims, see if other media outlets are debunking these claims.
It takes a bit of effort, but it is possible to do.
The FBI has proven themselves to be untrustworthy.
The justice department had proven itself to be untrustworthy.
No person or organisation is infallible. Mistakes are sometimes made. It doesn't mean you should write off completely the organisation.
Trump has proven himself to be untrustworthy.
Trump is defending himself, he has the ultimate motive to lie and distract. He doesn't seem to be making valid points when he argues he has declassified things merely by taking them out of the office and into his house. Or when he lies about Obama's handling of documents.
And when two untrustworthy sides clash you don't really know who to believe.
Perhaps you need to learn how to research, how to verify, how to debunk? How to tell journalism from opinion???
If the DOJ does not prosecute then I going to believe they don't have the evidence they claimed and they all lied to us AGAIN
Your assumption is that the raid was to get evidence in a case against Trump.
An alternative is that the raid was to get sensitive documents back to where they belong.
Also something important to remember that when investigations happen, when raids and such happen, they are before a court case has been held and before a judgement has been made.
The evidence has to be strong but not conclusive. Sometimes the raids and investigations don't turn up incriminating evidence.
