U.S. Mail is protected under the federal laws and the postal service is always reliable.
The coronavirus continues to pose a risk to Americans who want to vote in person at the polling station. Many are advocating that more voters cast mail-in ballots to avoid the crowd at polling stations. An old video still of a postal worker allegedly stealing a Trump's campaign sign in Townsend is being circulated by Trump supporters to the point that mail-in ballots can be misused, replaced, and can cause a delay. Trump has even said mail ballots are a dangerous thing for the country and lead to the most corrupt election.
The United States Postal Service fulfills the role of providing a secure, efficient, and effective way for citizens to use the mail in the electoral process.
It is one of the oldest and most trusted institutions in the U.S. Postal inspectors are mandated to safeguard all the mails and can enforce more than 200 federal laws associated with U.S. mail. The United States Postal Inspection Service will ensure the safety of election mail. There is also a provision of up to five years imprisonment if postal workers unlawfully destroy or delay the mail. There are various checks to prevent fraudulent ballots. Further, The National Vote at Home Institute, a nonpartisan group, has published a guide to clear the doubts about the safety of mail-in ballots.
The video still is used to create confusion among the voters about the reliability of the USPS and is not related to an actual incident.
