is all lying a sin or is it ok to tell the police you thought the speed limit was 45 when you knew it was 30?

The bible was written by people by not god, all I need to say

In your example, you tell the policeman

'Hi, can you tell me why you pulled me over?'

They might ask you again, being aggressive,

'Do you know how fast you were going'

I would have to reply to them

'sorry, but when I drive it never seems very fast at all'

There is no lying, just truth here.

They will feel frustrated having to tell you about

the 45 vs. 30.

I would have to say to them

'I don't look well enough, and it could cause problems'

(I mean, I agree where it is possible).

I seem to get along with these people in these situations

because I look at it from their point of view.

You can tell the police whatever you like, it won't make any difference. If you tell them you didn't see the 30 sign you could be charged with driving without due care and attention as well as speeding. Forget about people who lied in the Bible and got away with it, they do not have to pay your speeding fine, you do.

If you tell the police anything you are an idiot!

The only reason the police ask you 'do you know why I pulled you over?" Is to try to trick you into confessing to violating the law... The only correct response is "No, Why did you pull me over?" or to just remain silent.

Yes, it is a sin and no, it's not OK.
