Answer by taking a quote from the following article:

LaBeouf was born in Los Angeles, California, as the only child of Shayna (nee Saide) and Jeffrey Craig LaBeouf. His mother is a dancer and ballerina turned visual artist and clothing jewelry designer. His father is a Vietnam War veteran who had numerous jobs. LaBeouf's mother is Jewish, and his father, who is of Cajun descent, is Christian.

On December 17, 2013, LaBeouf released his short film Howard Cantour.com to the Internet; shortly thereafter, several bloggers noted its close similarity to Justin M. Damiano, a 2007 comic by Ghost World creator Dan Clowes. Wired journalist Graeme McMillan noted at least three similarities in their article, one of which was that the opening monologue for the short and the comic were identical. LaBeouf would later remove the film and claim that he did not intend to copy Clowes but was instead "inspired" by him and "got lost in the creative process." He followed this up with several apologies via Twitter writing, "In my excitement and naivete as an amateur filmmaker, I got lost in the creative process and neglected to follow proper accreditation", and "I deeply regret the manner in which these events have unfolded and want @danielclowes to know that I have a great respect for his work". Clowes responded by saying "The first I ever heard of the film was this morning when someone sent me a link. I've never spoken to or met Mr. LaBeouf ... I actually can't imagine what was going through his mind." LaBeouf was criticized over his apology, with some sites such as The A.V. Club noting that the apology itself appeared to have been lifted from a 2010 post on Yahoo! Answers.  Since the initial discovery of the plagiarism of Clowe's work, LaBeouf's other work has come under scrutiny. News outlets reported that LaBeouf's comic books, Let's Fucking Party and Stale N Mate, had been plagiarized from Benoit Duteurtre's The Little Girl and the Cigarette and Charles Bukowski's Assault.  In January 2014, LaBeouf spoke about the plagiarism accusations with Bleeding Cool writer Rich Johnston, where he stated that he saw copyright laws as too restrictive and that it did not allow for ideas to flow freely. LaBeouf later tweeted a description of his next project, Daniel Boring (a reference to David Boring, another comic created by Clowes). The description of the project was also taken word-for-word from a description by Clowes of his comic. Clowes' attorney, Michael Kump, has since sent a cease-and-desist letter to LaBeouf's attorney, which LaBeouf posted on Twitter.

Did LaBeouf have an excuse for the similarities?
he stated that he saw copyright laws as too restrictive and that it did not allow for ideas to flow freely.
