It is not “illegal” to have an all-white, all-black, all-Asian, etc. jury if that’s the result of the empanelment process. What is illegal is intentionally excluding prospective jury members due to race, religion, ethnicity, etc. The U.S. Supreme Court ruled on this issue in Batson v. Kentucky in 1986. Take a look at the article below for a recent review of the process, and continuing issues related to jury selection.

As far as a change of venue (location) for a jury trial, the specific facts of the case must be considered. We can’t answer your question without the full details, not to mention we wouldn’t comment on this legal matter, since we don’t provide legal advice.
