'someone' instead of 'one'

[azz]

a. One cannot expect to be treated like everybody else without respecting the law.
b. Some cannot expect to be treated like everybody else without respecting the law.

c. One can find anything on the net these days.
d. Someone can find anything on the net these days.

Are (a) and (b) both acceptable? Do they mean the same?
Are (c) and (d) both acceptable? Do they mean the same?

Many thanks.

Yes to a) and c).

b) and d) would require 'some / someone' to be replaced by 'one' or 'you' to sound natural.

Also, 'without respecting' is understandable in the context it appears in, but it would be better style to write 'unless you respect' or 'unless one respects'. The 'you' version sounds friendlier than the 'one' version.
