(3) by proof of former statements inconsistent with any part of his evidence which is liable to be contradicted;
Explanation. –– A witness declaring another witness to be unworthy of credit may not, upon his examination-in-chief, give reasons for his belief, but he may be asked his reasons in cross-examination, and the answers which he gives cannot be contradicted, though, if they are false, he may afterwards be charged with giving false evidence.
