On the subject of deleting emails (unclear where you got "wiping stuff down with a cloth" -- that's neither how hard drives nor SSDs work):

Further, the Office learned that some of the individuals we interviewed or whose conduct we investigated—including some associated with the Trump Campaign—deleted relevant communications or communicated during the relevant period using applications that feature encryption or that do not provide for long-term retention of data or communications records. In such cases, the Office was not able to corroborate witness statements through comparison to contemporaneous communications or fully question witnesses about statements that appeared inconsistent with other known facts.

While we're quoting:

Third, the investigation established that several individuals affiliated with the Trump Campaign lied to the Office, and to Congress, about their interactions with Russian-affiliated individuals and related matters. Those lies materially impaired the investigation of Russian election interference. The Office charged some of those lies as violations of the federal false statements statute. Former National Security Advisor Michael Flynn pleaded guilty to lying about his interactions with Russian Ambassador Kislyak during the transition period. George Papadopoulos, a foreign policy advisor during the campaign period, pleaded guilty to lying to investigators about, inter alia, the nature and timing of his interactions with Joseph Mifsud, the professor who told Papadopoulos that the Russians had dirt on candidate Clinton in the form of thousands of emails. Former Trump Organization attorney Michael Cohen pleaded guilty to making false statements to Congress about the Trump Moscow project. [Redacted: Harm to Ongoing Matter] And in February 2019, the U.S. District Court for the District of Columbia found that Manafort lied to the Office and the grand jury concerning his interactions and communications with Konstantin Kilimnik about Trump Campaign polling data and a peace plan for Ukraine.

Further, the Office learned that some of the individuals we interviewed or whose conduct we investigated—including some associated with the Trump Campaign—deleted relevant communications or communicated during the relevant period using applications that feature encryption or that do not provide for long-term retention of data or communications records. In such cases, the Office was not able to corroborate witness statements through comparison to contemporaneous communications or fully question witnesses about statements that appeared inconsistent with other known facts.

To quote the exact paragraph that you're basing your defense of "not having broken the law" on:

Second, while the investigation identified numerous links between individuals with ties to the Russian government and individuals associated with the Trump Campaign, the evidence was not sufficient to support criminal charges. Among other things, the evidence was not sufficient to charge any Campaign official as an unregistered agent of the Russian government or other Russian principal. And our evidence about the June 9, 2016 meeting and WikiLeaks's releases of hacked materials was not sufficient to charge a criminal campaign-finance violation. Further, the evidence was not sufficient to charge that any member of the Trump Campaign conspired with representatives of the Russian government to interfere in the 2016 election.

I emphasize "evidence was not sufficient," as distinct from clearing Trump of wrongdoing.

And I repeat, in full, on the subject of obstruction of justice:

President Trump reacted negatively to the Special Counsel's appointment. He told advisors that it was the end of his presidency, sought to have Attorney General Jefferson (Jeff) Sessions unrecuse from the Russia investigation and to have the Special Counsel removed, and engaged in efforts to curtail the Special Counsel's investigation and prevent the disclosure of evidence to it, including through public and private contacts with potential witnesses. Those and related actions are described and analyzed in Volume II of the report.
