I've been asking a lot about backshifting of tenses for quite some time and I come across many articles/blogs where this so called rule is not always followed unlike notable grammar books.
The spokesperson said they have received a video evidence of their being "alive" as recent as September 27 and they were making all efforts to secure their release.
My question is, since the main verb is in the past tense 'said' don't you think that it should be 'had received' instead of 'have received'?
You see this is one such link. I can provide multiple links having same error (if I can call this an error). So my question is, if journalists are using such grammar then isn't it acceptable?
