Meaning of 「おれば」＆「大手を振る」


The following sentence and translation appear in my textbook (総まとめ 読解 N１,
p114):

> 視聴率さえとっておれば、どんな"やらせ" をやろうとも、メディアの責任を考えればモラルに反すると思うことをやっても、大手を振ることが出来る世界
>
> A world (media industry) where they irresponsibly manipulate the content and
> do things contrary to social mores, as long as a high rating can be
> obtained.

I wonder if someone could explain:

1) what/why is おれば used (I think it is いる but why おる？）

2) what is the meaning of 大手を振る, literally and how does it work in this
context?




おる is a less common variation of いる. While I do not think that it is
incorrect, I do not know why the quoted sentence uses おれば instead of いれば (or
おけば as Hyperworm suggested).

[大手を振る](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&p=%E5%A4%A7%E6%89%8B%E3%82%92%E6%8C%AF%E3%82%8B&dtype=0&dname=0ss&stype=0)
(sense [2]) describes how a person behaves proudly (without being ashamed of
anything).

I would translate

> 視聴率さえとっておれば、どんな"やらせ" をやろうとも、メディアの責任を考えればモラルに反すると思うことをやっても、大手を振ることが出来る世界

as:

> A world where they can live without shame while they fake facts and do
> things which seem to be against ethics given the responsibility of mass
> media, as long as they have a high audience rating

I have to say that the translation into English which you quoted is sloppy.
Where did メディアの責任 and 大手を振る go?

Moreover, just in case, I recommend you _not_ to consider that the quoted
Japanese sentence is well written. I think that it is written carelessly for
at least the following two reasons: (1) it is unclear _who_ is thinking in
メディアの責任を考えればモラルに反すると **思う** ; (2) やらせ is apparently one of the
メディアの責任を考えればモラルに反すると思うこと, and therefore listing these two in parallel does not
really make sense.
