But, if no one objects, letting in the evidence can still lead to a
reversal on appeal if doing so was «plain error», and the «plain error» or objection preservation analysis
on appeal becomes even trickier if the defendant representing himself objects to the evidence coming in, but for the wrong reasons - for example, objecting to inadmissible hearsay
on the grounds that it is irrelevant when it isn't irrelevant but is inadmissible, but mentions that the person questioned «wasn't even there» when the
statement was made.
