I overheard a person saying that he wanted to trash the alley. Then when I went outside to check I saw a pile of trash outside the trash bin and a man standing there. Even though I did not see that he did it, but I knew that he was the one who dug up the trash from the trash bin and littered the alley. If I said that the man did it, would my action be considered an allegation or an accusation? Thanks.
