matches syntax is incorrect.Also there is no 6th ($5 refers to 6th field in the schema,positional notation starts from $0) field that has "false" in it.Use the correct field and the right syntax.Assuming 6th field has "false" in it, then this is how you would apply the filter on it.
uniq_arrest = FILTER LoadHomicide BY ($5 matches '.*false.*');
