Sniffing Public IP (Hackers tricks for protection)

So, I basically want to know how a hacker could sniff a public IP address at my office if they are outside my network. I have tried a few tools, to no avail and even though I sniffed perfectly within my network, I cannot figure out how I can see the unencrypted traffic while I am outside. Would someone literally need to be on my network to see this unencrypted traffic that is being sent out into the public internet?

My ultimate goal is to get something tangible to show the bosses, as far as what we are sending unencrypted and why security is important.

Basically, you would have to be on the same subnet (be in the same range of IP addresses given by the ISP) to be able to do this. Even so, many ISPs have security features that prevent this from happening. However, anyone at the ISP can easily see the data, so an employee of the ISP could misuses sensitive information acquired in this way. So even if your ISP implements security features to prevent hacking, they themselves can easily hack you. So, yes you do need encryption for all sensitive data.

Sniffing is a function of Layer 2 as the network interface will have to be in promiscous mode or a network tap wioll have to be used - thus for someone to sniff your traffic they have to be a part of your layer 2 broadcast domain. That way they will capture L2 to L7 data. Someone from outside your network cant just decide to target external traffic leaving from your router for sniffing.
