Explanation:

During the Red Scare, politicians (like those involved in McCarthyism) were constantly making claims about communists being present in the country. However, they often provided little to no solid evidence. This created an atmosphere of paranoia. People didn't know who to trust because there was a sense that anyone could potentially be a communist (as per the unfounded accusations), but there was no clear - cut way to verify these claims. This led to a breakdown of trust among neighbors and within communities.
