" The release stated that Bach had been on the run since the past 50 years."
Once upon a time the printed word was considered to be the epitome of language grammar. But it is depressing to see the print as well as the web full of linguistically handicapped reporters. Read the sentence pasted above. This should have been '....for the past 50 years'.
What a pity!! the basic grammer is f....d by these reporters.
